1993 is the main member of the eighth five-year plan project "Study on the Structure, Function and Dynamics of Mountain Forest Ecosystem", and is responsible for a sub-project research. 1995 Deputy Head of the National Natural Science Foundation Project "Study on the Relationship between Vegetation Succession and Environment in the Glacier Retreat Area of Gongga Mountain". 1996 presided over the ninth five-year plan of China Academy of Sciences, the formation mechanism of subalpine dark coniferous forest productivity, and 1996 China Academy of Sciences, the contribution and response of alpine forest ecosystem to global change, and participated in the national key basic research and development planning project (973 plan), the formation and evolution of the Qinghai-Tibet Plateau and its effects on environment and resources.50000.000000000606 In 2002, he presided over the national basic research (pre-research in 1973) on "Topographic uplift and its influence mechanism on Gongga Mountain ecosystem and its function" and the important direction project of knowledge innovation project of China Academy of Sciences on "Forest vegetation change and its hydrological effect". From 2003 to 2005, he served as the main member of the national natural science foundation project "Study on watershed scale effect and distributed hydrological model of forest hydrological effect". In 2003, he participated in the national key basic research and development plan project (973 plan) "Impact of climate change and land cover on water resources in typical areas of the upper reaches of the Yangtze River". In 2006, he participated in the theme of "Response of Forest Ecosystem to Climate Change and Environmental Effects", an important direction project of knowledge innovation project of China Academy of Sciences, and in 2007, he participated in the national key basic research and development plan (973 plan) project "Dynamic process of China cryosphere and its influence mechanism and adaptive countermeasures on climate, hydrology and ecology", and was responsible for "Influence of frozen soil and snow change in source areas of rivers and lakes on ecosystem functions". In 2007, he participated in the "Soil Inventory and Pollution Investigation in Xizang Autonomous Region" of the State Environmental Protection Administration, and was responsible for the "Soil Inventory and Pollution Investigation in Linzhi Area of Xizang Autonomous Region" project. In 2008, he was in charge of the national natural science foundation project "Study on carbon dynamics of vegetation primary succession sequence in Gongga Mountain glacier retreat area".
