Soil Ecology, Restoration Ecology, Forest Ecology

Over the years, the focus has been on the study of soil ecological functions during the restoration and reconstruction of the fragile mountain ecosystem in the eastern Tibetan Plateau, starting with the key issues of soil degradation in the alpine altitudinal zones (arid valleys, subalpine and alpine zones), and in-depth studies on soil structure, function and restoration processes have been carried out. The evaluation of soil structure, function and succession trend of alpine forest cut land was completed successively. The evolution process, characteristics and fertility degradation mechanism of subalpine spruce plantation were revealed, and strategies and techniques for improving ecological functions (diversity, soil fertility and carbon sequestration) of low-efficiency plantation were proposed. The spatial and temporal variation pattern, regularity and characteristics of climate, soil structure and fertility in the arid valley of Southwest China were described. Ecological restoration technologies such as risk identification, early warning, habitat (soil) reconstruction, substrate improvement, native species breeding and community allocation in the disturbed areas (slag fields, slopes, etc.) have been carried out in major projects such as Cheng-Lan-Lanzhou Railway and Sichuan-Tibet Railway. My current main interests are:

[1]      Restoration of degraded ecosystems: research on restoration process and ecological function improvement technologies, including formation of soil aggregate structure, organic carbon accumulation mechanism and sinks in restoration process; Diversity of soil organisms (microorganisms, nematodes, hopping insects, mites, protists, etc.), improvement of ecological functions and regulation and management techniques.

[2]      Ecological restoration of major projects: identification, formation and evolution mechanism and early warning technology of ecological environment risks of construction projects in complex and dangerous areas; Major engineering construction/mining disturbed area ecological restoration, soil matrix improvement, pro-growth functional microbial microbial agent research and development, native species breeding and community allocation and other technologies.

[3]      Soil improvement of farmland system: efficient utilization of organic residues in farmland (tea orchard) and carbon sequestration technology; Soil improvement technology of low-yield orchard; Soil biological health evaluation of characteristic agricultural products.
