Abstract:
In order to improve the ecological and economic functions of massive artificial cypress plantations in the hilly areas of central Sichuan, thinning experiments with different intensities were carried out to explore the suitable thinning intensity and stand density, which provided scientific reference for the precise improvement of the quality of low efficiency protective forest and sustainable management in this area. The artificial cypress plantations with canopy density ≥ 0.8, understory shrub coverage ≤ 20%, herb coverage ≤ 30% in 35−40 years were selected as the research objects, and three thinning intensities (10%−15%, 15%−25%, 25%−35%) and control (no thinning) were set up by random block method. 20 sample plots (5 for each thinning intensity) with the size of 20 m × 20 m were set up after 12 years of thinning. Tree stand growth factors, shrub and grass biodiversity, natural regeneration seedlings, litter accumination and water holding-capacity, soil physical and chemical properties were investigated and measured. Finally, the sample plots were evaluated comprehensively based on principal component analysis. The results showed that: (1) The growth of the remaining trees was significantly promoted after thinning. Compared with the control, the current annual increment of tree height, DBH and volume in thinned forest stands increased by 4.48%, 17.91%, 58.21%, 49.06%, 122.64%, 201.89% and 18.21%, 53.30% and 95.24% for thinning intensity of 10%−15%, 16%−25%,26%−35%, respectively. (2) The richness, Simpson index and Shannon-Wiener index of shrubs and herbs in thinned forests were higher than those of the control. Particularly, for thinning intensity of 26%−35%, the richness of shrubs and herbs, Simpson index and Shannon−Wiener index increased by 68.00%、108.00%、131.23%、 78.74%、134.98% and 179.73%, respectively compared with the control. (3) The number of seedlings in each height grade in thinned forests was higher than that of the control. Taking thinning intensity of 26%−35% as an example, the number of natural regeneration seedlings of < 10 cm, 10−30 cm, 30−50 cm and 50−150 cm were 83.78%, 80.00%, 83.33% and 72.09% higher than that of the control respectively. (4) The total litter volume in the forests with different thinning intensity was in the order of 26-35% (3.86 ± 0.10 t. hm−2) > 16−25% (2.93 ± 0.07 t.hm−2) > 10%−15% (2.06 ± 0.13 t. hm−2) > control (1.40 ± 0.06 t. hm−2). The maximum water-holding capacity, maximum interception amount and effective interception amount of litter in thinned forest stands were higher than those of the control. The maximum water-holding capacity, maximum interception amount, and effective interception amount in 26%−35% thinned forest was 1.54, 2.75, 2.76 times of the control. (5) The soil bulk density in different thinning intensity was ranked as 26%−35% < 16%−25% < 10%−15% < control. The order of soil capillary porosity was 26−35% > 16−25% > 10%−15% > control. The ranking of soil saturated water holding capacity was 16%−25% > 26%−35% > 10%−15% > control. The pattern of soil total C, total P and total K content in each treatment was consistent, with the order of 16%−25% > 26%−35% > 10%−15% > control. The total N content and organic matter content in different thinning intensities were as follows: 26%−35% > 16%−25% > 10%−15% > control. (6) Based on the principal component analysis, the comprehensive evaluation scores for the four thinning intensities were ranked as 26%−35% > 16%−25% > 10%−15% > control. The suitable thinning intensity of artificial cypress plantations in the hilly areas of central Sichuan was 20%−35%, that is, the number of reserved trees was 1700−2100 indv · hm−2.

Abstract:
The delayed blastocyst implantation, the rapid fetal development and the reproductive strategy of giving birth to short size cubs in autumn are closely related to the energy content and nutrients in the food structure of female giant pandas during pregnancy, thus forming the unique foraging behavior pattern of wild giant pandas. That is to say, wild giant pandas take bamboo shoots and young bamboo leaves rich in energy and nutrients as their staple food, and feed on a small amount of bamboo stems, bamboo branches, old bamboo leaves and different bamboo species, and migrate vertically with the temperature changes of the habitat environment. In this paper, the coupling energy-nutrition-temperature correlation effect mechanism between reproductive strategies and foraging behavior of giant pandas was summarized and demonstrated in the following four aspects: seasonal change pattern of habitat climate and vertical migration characteristics of wild giant pandas, phenological regularity of subalpine bamboos and foraging behavior habits of wild giant pandas, nutrition and energy differentiation of staple bamboo organs and reproductive physiological strategies of wild giant pandas, and physiological basis of nutrition and energy of staple food bamboo.

Abstract:
The aim of this study was to study the nutrient elements dynamics during litter decomposition in Cunninghamia lanceolata forests with different C/N ratios, so as to provide reference for scientific management of Cunninghamia lanceolata forest. The decomposition bag method was used to observe Cunninghamia lanceolata litter decomposition for 300 days. Four kinds of exogenous C/N treatments were set up: C/N ratio 60.86 (CK), C/N ratio 40.57 (N1), C/N ratio 30.45 (N2), C/N ratio 20.25 (N3). The nutrient contents in the decomposition process of Cunninghamia lanceolata litter in different stands were determined and analyzed. The results were as follows: (1) During the decomposition of Chinese fir litter, the C/N and C/P ratios were lower than the initial value, while the N/P ratio was higher than the initial value; (2) The concentrations of N, P, Ca and Mn were higher in CK treatment, and there were significant differences in the concentrations of P, Ca and Mn among different treatments; (3) During the litter decomposition, C, K, Ca and Mg all showed nutrient release, N showed nutrient enrichment, and P and Mn showed enrichment phenomenon during 180-300 days of decomposition, but on the whole showed nutrient release; (4) Decomposition time had great influence on seven elements (N, C, P, K, Ca, Mg, Mn) and three element ratios (C/N, C/P, N/P). There was a significant negative correlation between N and stand, a significant positive correlation between C/N and stand, a very significant negative correlation between different C/N treatments and Mn, and no significant correlation between other elements and stand and C/N treatments. (5) The retention of understory vegetation was useful for the release of C, K and Mg, while removal of understory vegetation is useful for the enrichment of N, Ca, P and Mn. During the 300-day litter decomposition process, exogenous nitrogen had a low promoting and high inhibiting effect on Cunninghamia lanceolata litter decomposition of , and with the extension of decomposition time, the promoting effect weakened and the inhibiting effect enhanced. Cunninghamia lanceolata litter decomposition required a low C/N ratio and a large demand for phosphorus. The research results could provide scientific basis for the management of Cunninghamia lanceolata forest.

Abstract:
Based on the desertification monitoring data and soil data of Zoige county in 2009 and 2014, and with the support of GIS technology, the distribution and dynamic changes of desertification in Zoige county were quantitatively analyzed, which provided scientific basis for the countermeasures of desertification control and ecological environment construction. In addition based on GIS, the study area was divided into desertification prevention and control zones, which provided more intuitive and accurate judgment and decision-making means for desertification control. The main results were as follows: (1) The distribution of desertification patches was aggregated and the spatial heterogeneity was obvious; (2) The clustering of monitoring patches with high desertification degree was obvious, which indicated that the patches with high desertification degree were aggregated in space; (3) The desertification trend was expanding to the northwest, especially to the Yellow River and Heihe River. Within 6 km of the river channel, about 70% of the land with obvious desertification trend and 60% of the desertified land were included; (4) The desertification land in the two stages of was mainly light sandy land, which indicated that land desertification in Zoige county was still in the initial stage, which was a favorable period for desertification control; (5) The research area was divided into key control areas, general control areas, general protection areas and potential protection areas. Finally, the control strategies were put forward

Abstract:
Monochamus alternatus Hope usually has one generation every year under natural conditions in the area of Dazhou City, and the larval stage consists of five instar. A few (0.95%) newly discovered species have one generation every two years (which has not been reported in China). The wintering period is from early November to late March of the next year, the larval stage is 292-355d, the pupal stage is from early April to early April, and the pupal stage is from 11 to 28d. The emergence of the pupal stage is from late April to late April. The peak of emergence is from late May to late June. Mainly concentrated in the weak pine dry high transverse groove to spawn, 1 ~ 8 m interval 5 cm below the rare groove, generally 1 slot to spawn 1 grain, two in individual, newly discovered a few upper bark smooth without groove, the egg laying pipe can be directly inserted into the subcutaneous cambium spawn in the country (this rare reports), die on the number of groove rate of about 24.8%; The egg-laying period is 8~14 days, and the egg-laying period is from mid-May to mid-September. The number of female adult egg-laying grooving ranges from 109 to 201, and the number of egg-laying varies from 50 to 150. The larvae hatched from the eggs have no pupation and emergence in the current year. The larvae validity was about 79%. The adult life span was 34-58 days for females and 35-66 days for males. The ratio of female to male was 1∶0.89. The larvae of 1 pouch type wintered in xylem burrow every 2 years, and experienced 2 overwintering periods (upper overwintering period for young larva and lower overwintering period for older larva). They pupated in early May, and emerged into adults from mid-May to early June. Prevention and control measures to perfect timing: artificial deforestation destroyed measures in the middle of that year in early November to April the following year, physical prevention and control of hanging set traps for adult eclosion early in late April, biological control spraying high spore hundred anisopliae should be brought forward to pupal stage of early April, chemical prevention and control of thiazole phosphorus microcapsules powder for feather peak in late may to mid-june.

Abstract:
To investigate the water holding capacities of Phyllostachys praecox litter, the water holding characteristics of litter (undecomposed layer and decomposed layer) under two main bamboo plantations were studied by indoor soaking method. The results showed that the maximum water holding capacity, maximum moisture rate and maximum water absorption rate of Neosinocalamus affinis undecomposed layer were 5455.76 g·kg−1, 701.99% and 9679.98 g·kg−1, respectively. Those of Neosinocalamus affinis decomposition layer were 5720.91 g·kg−1, 715.99% and 11372.6 g·kg−1, respectively. Those of Phyllostachys praecox undecomposed layer were 4281.82 g·kg−1, 510.00% and 7464.16 g·kg−1, respectively. Those of Phyllostachys praecox decomposition layer were 6970.35 g·kg−1, 900.07% and 10980.26 g/kg, respectively. The analysis showed that the maximum water holding capacity, maximum moisture rate and maximum water absorption rate of Phyllostachys praecox decomposition layer > those of Neosinocalamus affinis decomposition layer > those of Neosinocalamus affinis undecomposed layer > those of Phyllostachys praecox undecomposed layer. It could be concluded that litter decomposition layer whichwas decomposed by soil animals, soil microbe, and other decomposers had stronger water holding capacity and water absorption rate than undecomposed layer. The litter layer under bamboo plantation was an important structure layer for water holding, water conservation, overland flow retardation and preventing soil erosion. After decomposition, the litter of Phyllostachys praecoxhad better hydrological effect than that of Neosinocalamus affinis litter.

Abstract:
In order to understand the plant species composition and the relationship between plant functional traits and environmental adaptability on uninhabited islands, the field investigation and data consulting were conducted on six uninhabited islands in Pingtan District. The results showed that: (1) The small area of uninhabited islands led to fewer species. A total of 70 species of vascular plants belonging to 41 families and 70 genera were found on six uninhabited islands in Pingtan. The investigated seed plants were all angiosperms, among which Compositae (9 species, 9 genera) and Gramineae (7 species, 7 genera) were dominant families. (2) There were 19 alien invasive species, accounting for 27.14% of the total species, with Compositae and Gramineae as the main species. (3) Herbs were the dominant plant growth types in the six uninhabited islands of Pingtan. In terms of life form, high buds plants were the most, and cryptobud plants were the least. In terms of leaf functional traits, leathery leaves, small leaves, single leaves, whole leaves and hairy leaves were the most. The main types of fruits were dry fruits such as capsule, achene and drupe. The main ways of seed dispersal were wind dispersal, self-dispersal and other abiotic dispersal. Through this study, the composition and functional traits of plants in the six uninhabited islands of Pingtan were understood, which could provide reference for the protection, development and rational utilization of the ecosystem in the study area.

Abstract:
In this study, Tricholoma matsutake from 5 counties and 26 towns in Ganzi Prefecture was used as the research object. The heavy metal content, soil pH value, organic matter content in Tricholoma matsutake were measured, and the influencing factors of heavy metal accumulation were analyzed. The results showed that there were significant differences in the content of heavy metals in Tricholoma matsutake and soil samples collected from different places. The correlation coefficient of heavy metals content between soil and Tricholoma matsutake was 0.2<R<0.5, which indicated that there was a positive correlation. The arsenic (As) content in Tricholoma matsutake increased with the increase of soil acidity and organic matter content, while the accumulation of lead (Pb) was the opposite, that was, the higher the altitude, the higher the Pb content. Therefore, soil and altitude could affect the accumulation of heavy metals in Tricholoma matsutake.

Abstract:
On the basis of the research on the site condition of mineral yellow soil in the early stage, the purple soil walnut planting area in Xide County of Liangshan Prefecture was selected to carry out the fertilizer contrast experimen, in order to put forward reasonable fertilization suggestions for walnut planting in the purple soil widely distributed area. The 4-year-old "shuoxing" saplings and 10-year-old hanging fruit trees were selected as the experimental materials, and four treatments (T1: no fertilization, T2: application of common compound fertilizer, T3: application of special inorganic fertilizer, T4: application of compound microbial fertilizer) were set up to explore the effects of special compound microbial fertilizer on the plant height, fruit yield, quality and economic benefits of young trees. The results showed that the application of special compound microbial fertilizer could increase the height and fruit yield of young walnut trees. The growth of young walnut tree height and fruit yield in purple soil was higher than that in mineral yellow soil. The application of compound fertilizer was 38.03% higher than that of no fertilizer, 27.27% higher than that of common compound fertilizer and 10.11% higher than that of inorganic special fertilizer. The yield of walnut fruit increased by 44.56% and 28.04% compared with no fertilizer and common compound fertilizer, and the transverse diameter, weight, kernel yield, fat content and protein content of walnut fruit increased by 10.99%, 14.89%, 10.31%, 8.09% and 7.27%, respectively.

Abstract:
In order to explore the response mode of Phoebe Zhennan seedling growth to container types and sizes, a two-factor (container type and container size) experimental design was carried out in this study. 1-year-old Phoebe zhennan seedlings were selected as the research object, and the height of seedlings and ground diameter were measured at the end of the growing season, and the ratio of height to diameter was calculated, so as to screen the suitable container type and size for the cultivation of improved Phoebe zhennan seedlings. The results showed that the growth of seedling height was more affected by container type, while the growth of ground diameter was more restricted by container size. The seedling height and ground diameter produced by the 10 × 15 cm plastic seedling bag were higher, and the height to diameter ratio was significantly lower than that of most other types and sizes (P＜0.05). Consequently, considering the growth quality and economic benefits of seedlings comprehensively, it is recommended to choose 10 × 15 cm plastic seedling bags in actual production and application to cultivate improved varieties and strong seedlings.

Abstract:
The growth performance and fruiting quantity of different pecan varieties introduced to southern Sichuan were investigated. The results showed that the pecans grew sturdily and developed normally. The male and female flowering periods of pecans were from April 6 to May 8. After the grafted seedlings were planted, most varieties began to fruit at 4 years, and the highest yield per plant reached 1.24 kg at 5 years. Preliminary analysis indicated that the pecan had good adaptability to the climate environment in southern Sichuan, and was suitable for planting and developing. In the short term, No. 29, Weston, and No. 761 could be used as the main planting varieties. No. 21 and No. 35 could be used as the pollination varieties to further expand the scope of regional trials.

Abstract:
In order to improve the graft survival rate and shorten the seedling breeding time of Camellia oleifera. Effects of scions with different lignification degrees, different planting depths, different grafting time, different binding materials, and different height of small shed on the graft survival rate and growth amount of Camellia oleifera were studied from 2019 to 2020. The results showed that: (1) The survival rate, ground diameter and height were affected by the five factors above. The survival rate of lignified scion was the highest about 75.56%, which was significantly different from that shoots. The ground diameter of seedling height was also the largest at the five time periods. (2) In terms of different planting depths, the highest survival rate and the highest ground diameter was the depth of 6cm, which was significantly different from that of the control. Moreover, more branches were appeared in all three treatment groups, which indicated that they could formed faster, leave the nursery earlier, and get into the forest earlier. (3) In the height test of small arch shed experiment, the survival rate of small shed height of 40 cm was the highest, reaching 78.52％, and the average seedling height was the largest, which was 3.1 cm different from the minimum seedling height (that is, the height of the small arch shed is 30cm), and the difference is significant. In terms of ground diameter, the average ground diameter of treatment B (the height of small arch shed is 35cm) is the largest, which is significantly different from that of treatment C. (4) In the experiment of different binding materials, the survival rate and seedlings height of aluminum foil as binding material were higher than those of grafted seedlings bound by plastic film, and the survival rate of aluminum foil was 85.56%, which was 25% higher than that of plastic film, with significant difference. But the difference of ground diameter was not significant. (5) In different grafting times, the grafting on May 27 was significantly different from other experimental groups, with the highest survival rate, seedling height and biomass accumulation, which was significantly different from the grafting on June 27 and July 10, indicating that the best grafting time for the grafted seedlings of Camellia oleifera bud rootstock was in May, and the grafting effect in June and July was not good.

Abstract:
Taking bamboo sawdust as the raw material, various solid acids were used to catalyze the biomass liquefaction, and the effects of different acid strength, acid amounts and acid types on the liquefaction rates and component contents of bamboo sawdust were studied. The acid strength, acid amounts and the surface acid properties of the solid acid were analyzed by ammonia temperature program desorption method (NH3-TPD) and pyridine infrared spectroscopy (Py-IR). The results showed that the more strong acid sites corresponding to the solid acid, the higher liquefaction rate of bamboo sawdust. When the solid acid was used to catalyze the liquefaction of bamboo sawdust, lignin and hemicellulose began to liquefy at first, and the cellulose content in the solid residue increased. When the liquefaction of bamboo sawdust was catalyzed with solid phosphoric acid (SPA) with the most strong acid sites (1.21 mmol·g-1), , the liquefaction rate of bamboo sawdust could reach 62.0%, and the glucan content in the residue after liquefaction could reach 83.38%.

Abstract:
With the rapid development of economy, a large number of high-voltage power transmission lines were routed across the forest, which brought the fire risks of forest fire. Now, many current studies focused on the potential impact of forest fires on transmission lines, but they ignore the fire hazards caused by transmission lines themselves. By introducing the current forest fire risk assessment and zoning research of transmission lines, the paper analyzed the advantages and disadvantages of satellite remote sensing, laser radar and wireless sensor monitoring technologies in transmission lines and their application status, so as to provide a new idea for transmission line designers and construction personnel to reduce the forest fire risk caused by transmission lines. It was also considered that most of the existing research focused on the online monitoring and early warning of forest fires on transmission lines, and the research on forest fire prevention design and construction measures of overhead transmission lines should be focused in the future to improve the pre-disaster prevention ability of transmission lines.
