He has successively obtained a bachelor's degree in forestry from Sichuan Agricultural University, a master's degree in silvculture, and a doctor's degree in ecology from Shenyang Institute of Applied Ecology, Chinese Academy of Sciences. He worked as a visiting professor at Griffith University in Australia from 2003 to 2004, and as a senior visiting scholar at Yokohama National University in Japan in 2005. His main research interests include forest ecology, ecosystem ecology, ecosystem management, and biodiversity conservation. He have led and completed multiple research projects such as the National Natural Science Foundation and the National Key Research and Development Program, and have published nearly 200 papers. Among them, He have published over 70 papers in international important journals such as Nature, Science of the Total Environment, Geoderma, Catena, Diversity and Distribution, Plant and Soil, Soil & Tillage Research, and Ecological Indicators, etc. Some of his papers have been cited in top international academic journals such as Science and Nature. He has won two ministerial and provincial science and technology achievement awards, and won honors or titles such as outstanding experts with outstanding contributions in Sichuan Province, academic and technological leaders in Sichuan Province, advanced individual in Sichuan Province in building ecological barriers in the upper reaches of the Yangtze River, the ninth "excellent environmental science and technology workers" of the Chinese Society of Environmental Sciences, and special government subsidies of the State Council. 41 graduate students with master's and doctoral degrees, including 5 foreign doctoral graduates successfully graduated and obtained their degree certificates under under his guidance.

He used to be the deputy director, branch secretary and director of the Ecological Research Center of Chengdu Institute of Biology, the Chinese Academy of Sciences, the chief scientist of the Ecological Process and Biodiversity Research Group, the secretary-general of the Sichuan Ecological Society, the executive director of the Sichuan Geographical Society, the director of the Sichuan Forestry Society, the deputy director of the Ecological Professional Committee of the Sichuan Environmental Science Society, and the deputy director of the Plant Allelopathy Professional Committee of the Chinese Plant Protection Society. He is now a member of the Academic Degree Committee of Chengdu Institute of Biology, the Chinese Academy of Sciences, professor (Level II), doctoral and master's supervisor.
