I am now a professor and doctoral supervisor of Anhui University of science and technology. We have been devoted to the study of element geochemical behavior and environmental effect of water and soil medium in mining area for a long time. In recent years, taking the soil environmental material flow of mining area as the research object, considering the "positive" and "negative" two-way effects of mining activities and human restoration intervention, combined with the particularity of soil reconstruction, disturbed soil structure of mining area and the complexity of environment, the soil biological (crop) system of mining area was revealed from different scales such as mining area (region), long-term location experimental area (field block) and soil column Based on the geochemical behaviors of heavy metals, water and salt and their driving mechanisms, the eco-environmental effects in the process of migration, transformation, release, analysis, production and discharge and their guiding significance for the reclamation and ecological restoration of the mining area were clarified. The indicating role of biology in the reconstruction of soil quality in the mining area and the key technologies and parameters of vegetation restoration in the mining area were put forward. It enriches and promotes the development of land reclamation, ecological restoration and mine environment management in mining area to a certain extent. He is a member of the special committee of land use engineering of Chinese society of agricultural engineering, an expert of mine geological environment management and land reclamation plan of Ministry of natural resources, and an expert of Anhui Provincial Department of natural resources and science and technology. Anhui University of science and technology environmental science and engineering discipline leader, Anhui Province universities (Professional) top talent. Won 3 awards from Coal Association. Nearly 100 academic papers have been published. Presided over and participated in 10 national or provincial level projects such as National Natural Science Foundation of China, national key R & D program, Ministry of land and resources, and nearly 20 projects entrusted by local governments or enterprises. He has written or participated in the compilation of nearly 20 academic works and textbooks. Presided over and participated in 10 national and industrial standards of mine ecological restoration and solid waste comprehensive disposal.
