Abstract:
As an important part of the forest resources,the woodland is the basic carrier of forests,a key component of natural landscape and principal ecological land. With urban expansion,a large number of woodlands and wetlands have been exploited for other purposes,thus resulting in constant change of spatial distribution of the woodland landscape; this change has further caused great impact on the regional ecological security pattern and macro-ecological environment. The study of ecological security pattern's response to the change of woodland landscape patterns has shown that the woodland area was declining during 1985-2006 in Chengdu city; the entire forest landscapes tended to fragmentation and its shape became simpler. The analysis of woodland pattern changes in different ecological security levels has indicated that the woodland area in high security zone during each period is much larger,but the fragmentation level is low. The woodland area in low security zone is the smallest and the number of patches is the minimum. The changes of woodland area and patch number has a positive correlation with the ecological security situation. However,the shape complexity of woodland patch has no obvious correlation with the location in security zone.

Abstract:
The hilly areas of central Sichuan Basin are located in the upper reaches of the Yangtze River. The stand in these areas is an important component of the ecological barrier for the upper reaches of the Yangtze River. The Shrub and grass layers as an indispensable part of forest ecosystems have a great function on improving the interception of runoff and maintenance of biological diversity and conserving water and soil. In this paper,the main stand types (mixed alder and cypress plantation and pure cypress forest developed from mixed alder and cypress plantation) are used as the study objects,and researches are conducted on the species diversity of shrub and grass layers under the mixed alder and cypress plantation. These results will provide a theoretical basis for the species diversity conservation and the healthy management of artificial cypress plantations in these regions and similar areas.

Abstract:
Damaged mountain slopes and desertification,including hot or hot-dry valleys,degrading sands, poor rock lands,etc.,known as the earth's "ecological cancer",are the key areas of afforestation and ecological management in the world. Many difficult site types are located in the source regions of the Yangtze River and the Yellow River in China,and belong to "the river source" and "the ecological source" by their ecological function. The difficult sites would often cause the deterioration of the environment,water loss and soil erosion and land desertification,and even bring about serious threats on the economic development and human survival if no effective managements were conducted. Ecological engineering are the effective ways of solving stubborn environmental problems of difficult site types. In this paper,a summary description is given of the most advanced engineering techniques and means of ecological restoration,aiming to provide strong scientific support for the ecological restoration of difficult site types.

Abstract:
Late embryogenesis abundant protein(LEA) is one of the most significant drought-induced proteins. Lea genes express themselves not only during the period of seed maturation and dehydration,but also would increase when the plant vegetative organs are faced with different stresses. In this article,a brief description is given of the classes and characters,functions of LEA proteins and the structures and expressions of the lea genes.

Abstract:
Forest fire itself is a natural disaster,and is characteristic of sudden occurrence,and big damage,and relatively difficult for disposal rescue. In addition,due to the influence of the global climate anomaly,high temperature,drought,and windy weather in many regions of China increased,thus leading to forest fire risk raising. In this paper,taking Renhe District in Panzhihua City of Sichuan province as the research area,analysis is made of forest fire risk evaluation factors of the forest fire forecast system of various countries,and in combination with the actual situations of the study area,the fuel type,terrain and artificial influence are selected as forest fire danger division indices. With extraction of the classification information of fuel by remote sensing images,extraction of slope,aspect and altitude through DEM data,and buffer analysis is made of human factors. The factor weighted superimposed method is adopted to generate an integrated forest fire zoning map of Renhe District in Panzhihua City through making weight distribution for each division factor which have different impacts on the fire occurrence or spread. This zoning map can provide scientific valuable reference for the local forestry department in the deployment of resoures for forest fire prevention.

Abstract:
In recent years,a lot of trees of Pinus tabulaeformis forest have been found to be withered or dead in several regions in Xiaojin county and this phenomenon has a further spreading tendency. In this paper,analysis is made of pests and site conditions of P. tabulaeformis. The results have shown that the withered reason of P. tabulaeformis in Xiaojin is the result of the comprehensive function of pests and site conditions. Because of poor site conditions in Xiaojin,P. tabulaeformis growth is worse than other tree species,thus giving the opportunity for the invasion of pests,such as blight,pine needle rust,bark beetles and longicorn beetles,and causing the growth of P. tabulaeformuis to decline and even die. Therefore the effective measures should be adopted to control these potential disasters and strengthen the tending of the stand and the monitoring of pests.

Abstract:
In July and November of the year 2010,4 sampling sites were choosen,namely Wulingkeng (with an elevation of 900 m),Wanlilin (with an elevation of 1 100 m),Liyang (with an elevation of 1 300 m) and Baishanzu Station (with an elevation of 1 500 m),which are located at different altitudes, aiming to trap small mammals for studying the vertical variation of their communities. A total of 101 individuals of small mammals were captured,belonging to 2 orders,3 families,10 species. The results showed that capture rates and biomass at 4 altitudes had highly significant differences (P < 0.01). The dominant species,Niviventer confucianus,had the highest captured rate and a great percentage of the biomass,followed by Niviventer fulvescens. Similar to previous studies,both diversity and evenness of small mammals at middle altitudes (1 100 m~1 300 m) were higher than those at low and high altitudes. On the contrary, captured rate and biomass of small mammals at middle altitudes (1 100 m~1 300 m) were both lower than those at low altitudes and high altitudes. It was indicated that the comprehensive effect of habitat types at different altitudes and human disturbances in habitats might be the cause of this result.

Abstract:
In order to understand the effects of shading on the growth of Alnus formosana,100%,50% and 15% of transmittance were simulated according to the light regimes in the forest opening,forest gap and forest canopy. Studies were made of the growth and physiological characteristics of A. formosana seedlings planted in different shading treatments. The results showed that with shading intensity increasing,plant height and base diameter showed the trend of first increasing and then decreasing,while net photosynthetic rate(Pn),transpiration rate(Tr) and stomatal conductance(Gs) gradually reduced except for intercellular CO2 concentration(Ci). Under different shading conditions,chlorophyll a(Chla),chlorophyll b(Chlb) and total chlorophyll content increased with transmittance decreasing,however,carotenoids(Car) content,chlorophyll a/b(Chla/b) and lamina mass per unit area(LMA) were opposite. In addition,with the reduction of light intensity,soluble sugar exhibited first decreasing and then increasing,while proline(pro) content gradually increased in leaves of A. formosana seedlings. Therefore, it was suggested that A. formosana seedlings could not adapt to the high-light environments outside forest,but moderate shading,that is to say,canopy gaps would benefit the seedling growth. At the same time,it also provided a scientific reference for forestation,breeding and vegetation recovery.

In this paper,taking Fokienia hodginsii and Schima supeaba pure forests as a control,experimental analysis is made of the mixed density and ratio of Fokienia hodginsii and Schima supeaba mixed forest. The results have shown that mixed Fokienia hodginsii and Schima supeaba plantation is a better mixed combination. Analysis from the operating density B > A > C,afforestation density of 2 500 trees per hectare is favourable to Fokienia hodginsii DBH growth; in 10-year-old mixed forest from an average tree height growth analysis,Fokienia hodginsii displays a decreasing order of A > B > C. Fokienia hodginsii average height sequence from the mixed ratio analysis is B8M1 > B2M1 > B1M1 > B1MO. It is indicated that average tree height and average DBH of Fokienia hoginsii in mixed forest are greater than those in Fokienia hodginsii pure forest.

Abstract:
Studies were made of the plantation density of small wood Eucalyptus grandis (φ8 cm~10 cm) by randomized block design. The results showed that different planting density had no significant effect on the height increment of one to three years old Eucalyptus grandis trees. When the tree age was 3, the planting density had certain effect on Eucalyptus grandis diameter at breast height growth,and with the increase of the density,its diameter at breast height would decrease. The growing stock was maximum when the density was 1 666 trees per hectare. Therefore,the suitable density should be 1 666 trees per hectare when small wood Eucalyptus grandis was cultivated in Guang'an.
