Abstract:
Leaves are the main places for photosynthesis. Through photosynthesis, the energy fixed by photosynthesis is used for respiration consumption and assimilation, and the biomass in leaves is allocated at the same time of material production. This allocation is not a proportional change in biomass between stalks and leaves, but an allometric growth relationship between stalks and leaves, that is, the balance between stalks and leaves, due to the influence of their own and external factors. At present, there is no review on the response of intra-leaf biomass allocation strategies to life forms and leaf traits. This paper mainly discusses the response mechanisms of intra-leaf biomass allocation to different life forms, leaf types, leaf sizes, leaf shapes and leaf water content. Several aspects that need to be further studied in the future are proposed: (1) Explore the relationship between all or part of the supporting components and intra-leaf biomass allocation, and reveal how the supporting structure of different proportions affected the leaf biomass allocation strategies, and what kind of 'role' each supporting structure played in leaf biomass allocation; (2) Explore the relationship between phyllotaxis and biomass allocation, and reveal how the intra-leaf biomass was allocated during the carbon gain process of photosynthetic components under different arrangement modes, and how the leaf water and nutrient transport process under different arrangement modes affected the intra-leaf biomass allocation. (3) Explore the relationship between petiole and other supporting structures and leaf traits; (4) Explore the range of leaf economic spectrum (LES) and reveal whether LES includes the relationship between leaves and petioles.

Abstract:
A lot of climate and environmental information is recorded in tree rings. How to better dig out other environmental information contained in tree rings from multiple scales is one of the important scientific problems that need to be solved urgently. Tree rings are formed by the regular growth and changes of tree cambium cells in trees. Under harsh environmental conditions or when the environment changes, it will affect the normal activities of cambium, thus leaving some special traces in the tree ring structure, such as frost ring, false ring, shallow ring and missing ring and other abnormal structures. The formation of abnormal structure is closely related to climate factors such as temperature, precipitation, light, etc. In addition, the production of reaction wood and resin channels is mainly affected by mechanical external forces. By exploring the relationship between anomalous tree-tings and environmental factors, it is helpful to deeply understand the influence of extreme events on tree cambium activities. The characteristics of different types of abnormal structures, such as areas, tree species, seasonal conditions, formation mechanism and their application in extreme events, were summarized based on the relevant reports of abnormal tree-rings, which was helpful to understand the impact of extreme events on forests and the response mechanism of trees to extreme events from the physiological perspective. It is expected to provide new strategies and methods for future related research.

Abstract:
Most species of the genus Cassytha are confined in Australia, and a few species are found in Africa. However, Cassytha filiformis L. is a particular species is distributed all over the world in a pan-tropical manner. The purpose of this study is to simulate the potential suitable areas of this widely distributed species (C. filiformis) and narrow-range species, analyze the environmental differences of their suitable areas, and analyze the distribution pattern of the genus Cassytha diversity and the underlying causes, in order to provide basic information for the protection of forest diversity and the stability of ecological environment. The results showed that, based on environmental variables, the MaxEnt model had a high accuracy in predicting the potential distribution areas of the genus Cassytha. The area under the receiver operating characteristic curve (AUC value) was greater than 0.9 for both the training and test sets, indicating a good confidence in the predictions. Based on the contribution rate of environmental variables and the Jackknife method, the results showed that precipitation, temperature, and soil were the main factors limiting the distribution of the genus Cassytha species. The distribution of most narrow species were greatly affected by soil conditions, while the distribution of C. filiformis was not significantly limited by soil factors. Overall, the environmental factors affected the geographical distribution of the genus Cassytha species had suitable thresholds and narrow ranges, except for C. filiformis, which had the largest range of thresholds. It is currently tentatively hypothesized that the wide distribution of C. filiformis and the narrow distribution of the other species can be attributed to four reasons. Firstly, C. filiformis has strong environmental adaptability, and can tolerate a wide range of dominant factors that influence its distribution. Secondly, the distribution of this species is not limited by soil factors. Thirdly, the seeds of the C. filiformis can diffuse over a long distance. Lastly, this species has the ability to utilize a wide variety of hosts for its survival and reproduction.

Abstract:
It is of great significance to explore the fine root morphological characteristics and nutrient distribution patterns of Olea europaea for its introduction, cultivation, and production. By studying the morphological parameters such as fine root diameter, specific surface area, specific root length, and tissue density of five Olea europaea varieties in the Panxi region, as well as the chemical stoichiometric characteristics of carbon (C), nitrogen (N), and phosphorus (P), the differences in fine root morphology and nutrient content among different olive varieties in fine root order levels and their correlation with soil physicochemical properties were discussed. The research results showed that: (1) With the increase of root order level, the diameter of fine roots and tissue density showed a significant increasing trend, while the specific surface area and specific root length showed a significant decreasing trend; (2) The content of fine root C, C:N, and C:P gradually increased with the increase of root order, while the content of fine root N and P basically decreased with the increase of root order. Except for white olives, the overall trend of fine root N: P increased with the increase of root order level; (3) There was no significant correlation between fine root C content and soil physicochemical characteristics indicators. There was a significant positive correlation (p<0.05) between the fine root N content and soil C and P content, and a highly significant positive correlation (p<0.01) with soil C: N. There was a highly significant positive correlation (p<0.01) between the fine root P content and soil C, P content, and C: N, while there was a significant negative correlation (p<0.05) between the fine root P content and soil N: P. There was a significant negative correlation between fine root C: N and soil C: N (p<0.05), while there was no significant correlation between fine root N: P, C: P and soil physicochemical characteristics.

Abstract:
Plantation is an important part of forest ecosystem in northwest Sichuan. In order to understand the forest quality status of the two typical plantations with spruce (Picea asperata) and radiata pine (Pinus radiata) as the dominant species, the forest quality assessment was carried out by using factor analysis and cluster analysis. The research results showed that: (1) Four principal components were extracted by factor analysis, and the cumulative variance contribution rate of the four principal components was 76.877%, which could comprehensively reflect the forest quality; (2) The weight values of the four criterion layers were as follows: timber growth factor> understory shrub factor > stand canopy coverage> understory herb factor, indicating that timber growth factor had the greatest influence on the forest quality evaluation index system. (3) According to the comprehensive score of forest quality evaluation, the proportion of sample plots in each grade was 10% in excellent condition, 40% in good condition, 10% in medium condition and 40% in poor condition, respectively. (4) There are obvious differences in the quality of plantions of different tree species in northwest Sichuan, among which the quality of spruce plantations was "good" and that of radiant pine plantations was "poor". This study is helpful to grasp the forest quality status of plantations in northwest Sichuan, thus laying the foundation for accurate improvement of forest quality in the future.

Abstract:
The dynamic change of species diversity and the assessment of population status are very important for the scientific conservation of species. The eastern margin of Qinghai-Tibet Plateau is a global biodiversity hotspot in southwest China, which has important scientific research value and conservation status. In order to effectively evaluate the diversity and distribution pattern of large- and medium-sized mammals in the eastern Qinghai-Tibet Plateau, Xinlong County, which is the most representative county in this region, was selected as the main research area. The literatures and data related to infrared cameras published in this region since 2013 were systematically collected, and an infrared camera survey was carried out from December 2019 to October 2020. The results showed that there were at least 36 species of mammals in Xinlong County, belonging to 5 orders, 14 families, including 7 species of cats, 7 species of national level I and 16 species of national Level II key protected wild animals. According to the IUCN Red List, there were two species of endangered (EN), seven species of vulnerable (VU) and six species of near threatened (NT). During the monitoring and research over the years, Carnivore and Cetartiodactyla species were abundant, and 7 cats were still recorded at an interval of nearly 3 years. The relative abundance index (RAI) and grid occupancy (GO) of Leopard (Panthera pardus) ranked among the top 10. The relationship between the size of RAI and GO of seven cats was as follows: Leopard > Leopard Cat (Prionailurus bengalensis) > Eurasian Lynx (Lynx lynx) > Snow Leopard (Panthera uncia) > Asiatic Golden Cat (Catopuma temminckii) > Chinese Mountain Cat (Felis bieti) = Pallas's Cat (Felis manul). In this study, it was found that in different habitats and at different altitudes in different seasons, a variety of cats and main prey species were distributed, and the five cats except Chinese Mountain Cat and Pallas's Cat had different degrees of overlap with their main prey and disturbance factors in different seasons. The results of this study indicated that the overall population status of cats in Xinlong County on the eastern Qinghai-Tibet Plateau was good, food resources were abundant, and the entire ecosystem was in a healthy state. However, it is necessary to further strengthen the scientific control of disturbance factors in the main distribution areas of cats in the future. At the same time, the difficulties faced by the protection of rare and endangered wild animals represented by cats in Xinlong County were also pointed out, and the follow-up protection suggestions were put forward for reference.

Abstract:
China has a vast territory, spanning 6 climate zones and covering 8 main vegetation types, with extremely rich plant diversity and germplasm resources. The launch of the construction of Beijing and Guangzhou National Botanical Gardens indicates that the construction of China’s national botanical garden has entered a substantive stage. However, the development of modern botanical gardens in China started relatively late, and there is still a significant gap compared with foreign botanical gardens. Based on the analysis of the current situation of botanical gardens in China, it is proposed that botanical gardens should be divided into “national-regional-city” three levels according to the existing classification standards as soon as possible. On the basis of clarifying the orientation and characteristics of botanical gardens at all levels, reasonable additions or expansions should be made in the form of “main garden+satellite garden”, so that the functions of the three levels of botanical gardens have their own emphasis. At the same time, the government should play a good role in market supervision and regulation, improve relevant norms and standards, flexibly introduce social capital, and use the “PPP” model to promote the formation of a closed loop for the transformation of scientific and technological achievements in botanical gardens, so as to form a botanical garden system with Chinese characteristics and multiple social values with the National Botanical Garden as the core.

Abstract:
As a pioneer species in the primary succession stage, bryophytes play an important role in water conservation, soil conservation and biodiversity maintenance due to their unique physiological structure and dehydration recovery ability. In this study, three bryophytes including Racomitrium japonicum, Hypnum plumaeforme and Plagiomnium ellipticum in different habitats (grassland, shrub, forest and bare rock) were selected as the research objects. Based on field investigation and laboratory analysis, the ecological effects of dissolution activity, soil and water holding capacities of three typical bryophytes crusts on the post-earthquake restoration in the Jiuzhaigou National Nature Reserve were evaluated. The results showed that R. japonicum had the highest the carbonic anhydrase (CA) activity (50.5 U·g−1 DW), the maximum dissolution rate (4.8×10−4 t·km−2·a−1 CO2) and carbon sink content (2.12 mg ·m−2·a−1). Different mosses in different habitats had different soil consolidation capacity, among which the soil consolidation capacity of H. plumaeforme was the highest (3.1×103 kg·hm−2), and its maximum soil consolidation rate was more than 2 times of its own dry weight. In addition, the water retention capacity of P. ellipticum was higher than that of R. japonicum and H. plumaeforme. The water holding capacity of P. ellipticum was between 1100-1400 kg·hm−2, and the water retention rate was more than 8 times of its own dry weight. In conclusion, in the process of ecological restoration by using moss crusts, it is suggested to select specific bryophytes according to different stages and different habitat conditions from the perspective of ecological restoration such as soil formation, soil consolidation and water conservation, so as to accelerate the ecological restoration and reconstruction after the earthquake in Jiuzhaigou National Nature Reserve.

Abstract:
Due to the global warming, the spatial distribution pattern of pests has changed greatly, which increases the difficulty of pest prevention. In this paper, using MaxEnt model and GIS method, the potential suitable distribution area of Monochamus alternatus in China was simulated. At the same time, the distribution range and spatial arrangement in three climate scenarios (RCP2.6, RCP4.5 and RCP8.5), and the movement law of its mean center were predicted, compared and analyzed. The results showed that all AUC values were over 0.95, and the accuracy was in an "excellent" state. Under current conditions, the suitable range of Monochamus alternatus in China was 20-41°N, 90-125°E, which was distributed continuously from west to east and concentrated in the southeast of China. Under future climate scenarios, the moderately suitable area will decrease, while the lwo and high suitable areas will increase, and will spread to the high latitude and altitude areas, with RCP8.5 having the largest diffusion range. The mean center of the suitable area predicted to move northwest or northeast under different scenarios, and the migration trend was the most intense in the highest greenhouse gas emission scenario (RCP8.5). The results provide an effective means for rational zoning of Monochamus alternatus and a theoretical basis for coping with climate warming.

Abstract:
Based on the climate characteristics of subtropical regions, five high temperature gradients (36℃, 38℃, 40℃, 42℃, 44℃) were set up to shock Zoysia tenuifolia seedlings for 30 days (2 h/d). The effects of the shocks on growth and physiological response of Z. tenuifolia seedlings were studied by measuring plant height, tiller number, leaf area, biomass, chlorophyll and physiological active substance content. The results showed that: (1) High temperature shock significantly affected the morphological indicators, with plant height, leaf number, and total leaf area decreased at ≥38℃, but tiller number decreased at ≥40℃. The impact on morphological indicators was as follows: total leaf area>tiller number>plant height>leaf number>leaf thickness. (2) High temperature shock significantly affected biomass accumulation and distribution, when ≥40℃ total biomass and root to shoot ratio decreased, with biomass preferentially distributed to the aboveground portion. (3) High temperature shock significantly affected chlorophyll content, with a decrease in chlorophyll a content at ≥ 38℃ and a decrease in chlorophyll b at ≥40℃,but chlorophyll a/b was less affected. (4) High temperature shock significantly affected physiological substances. The higher the temperature was, the greater the activity of SOD and POD was, as well as the content of MDA and Pro. The magnitude of the impact was MDA>POD>SOD>Pro>CAT. The response of resistant substance content to different high temperatures varies greatly. In summary, high temperature shock affected the growth, meristem, and photosynthetic capacity of Z. tenuifolia. By regulating resistant substances to resist high temperature damage, it can withstand 44℃ high temperature shock and safely survive the summer.

Abstract:
The effects of different concentrations of calcium chloride (5, 10, 15 mmol·L−1) on the physiological characteristics of Prunus triloba seedlings under salt stress (0.4% sodium chloride) were studied with P. triloba Lindl. current year seedlings as experimental materials. The results showed that: (1) The SOD and POD activities in P. triloba seedlings were increased under salt stress, and the activities of this two protective enzymes were significantly increased in 10 mmol·L−1 calcium chloride treatment under salt stress, and the 15 mmol·L−1 and 10 mmol·L−1 treatments had no significant difference. (2) The chlorophyll content of P. triloba seedlings was decreased under salt stress, and 5 mmol·L−1 calcium chloride treatment did not significantly affected the chlorophyll content of P. triloba seedlings under salt stress, but 10 mmol·L−1 treatment significantly increased the chlorophyll content of P. triloba seedlings under salt stress. (3) Both 10mmol·L−1 and 15 mmol·L−1 calcium chloride treatment could significantly increase the net photosynthetic rate of P. triloba seedlings, but 5 mmol·L−1 treatment had no significant effect on the net photosynthetic rate of P. triloba seedlings under salt stress; (4) The activities of sucrose phosphate synthase and sucrose synthase in P. triloba seedlings leaves were increased under salt stress, but the activities of this two enzymes in P. triloba seedlings were significantly reduced in 10 mmol·L−1 calcium chloride treatment under salt stress. According to comprehensive analysis, 10 mmol·L−1 was the suitable concentration of calcium chloride to alleviate salt stress of P. triloba seedlings.

Abstract:
The Phellodendron chinense bark and leaf extracts were used as the control agent for Bletilla striata rust disease. The incidence rate, disease index, control effect and disease grade distribution of Bletilla striata rust disease under the treatment of the control agent were counted, and the control effect of Phellodendron chinense extract on Bletilla striata rust disease was discussed, and the prevention and control mechanism of Phellodendron chinense extract on Bletilla striata rust disease was clarified. The results showed that the incidence rate and disease index of Bletilla striata rust disease were the lowest under ZP50 treatment. In June, the disease index was Y50>CK>Y25>P25>ZP25>P50>ZP50. Compared with CK, ZP50 treatment had the best control effect, and the control effect was 93.64% in July. From the distribution of disease levels in June and July, the disease severity of Bletilla striata was weak under ZP50 treatment. The ZP50 treatment could control the critical degree of Bletilla striata rust and reduce the disease index by reducing the incidence of Bletilla striata rust and regulating the proportion of disease conditions of grade 1, 7 and 9. Overall, the control effect of Phellodendron chinense bark extract was better than that of Phellodendron chinense leaf extract, and the control effect of boiled Phellodendron chinense bark extract was better than that of uncooked Phellodendron chinense bark extract, and high concentration Phellodendron chinense bark extract had better control effect than low concentration Phellodendron chinense bark extract. Phellodendron chinense extract can be used as a green control agent for Bletilla striata rust disease.

Abstract:
The germination characteristics of Acer pentaphyllum seeds harvested for 1 and 3 years in Yajiang County, Jiulong County, Muli County, Jiulong Sanyagong and Kangding City in Sichuan Province were studied. The results showed that: (1) The seed germination rate of Acer pentaphylla was generally low (between 4.0% and 17.6%) in five regions, among which the seed germination rate in Muli County, Yajiang County and Jiulong County was significantly higher than that in Kangding City and Sanyagong in Jiulong. (2) The seed kernel percentage of Acer pentaphylla harvested for one year in five regions was low (between 36.8% and 45.2%), but there was no significant difference among regions. (3) The embryo viability of Acer pentaphylla seeds harvested for one year in five regions was classified into three categories: high (more than 95% in Jiulong County, Muli County and Kangding City), medium (91.7% in Sanyagong, Jiulong County) and low (53.3% in Yajiang County). (4) The water absorption of Acer pentaphylla seeds can be divided into three stages: rapid water absorption period, slow water absorption stage and stable water absorption stage. (5) The seed germination characteristics of Acer pentaphylla were affected by the storage time. The seeds of Acer pentaphylla harvested for 3 years in Jiulong County and Muli County could not germinate normally, and the seed kernel rate and seed embryo vitality decreased. In conclusion, the differences in seed germination characteristics of Acer pentaphylla from different provenances were related to embryo viability, and the prolongation of storage time would reduce seed embryo viability. In order to improve the success rate of artificial seedling raising of Acer pentaphyllum, it is suggested that the newly harvested seeds should be selected for seedling raising.
