A young scientist in Lanzhou University, mainly focusing on system equilibrium theory to find the patterns and the underlying mechanisms of dynamic ecosystems. Specifically, he is interested in topics on regime shift and early warning signals. As to the underlying mechanisms, he is particularly interested in ecohydrological processes and biological soil crusts. A wide range of data-obtaining approaches are employeed, including experimental, monitoring, observational data and process-based model. I mainly work on drylands, although not limited to it.
Dryland Ecosystem Stability
Under the influence of global change, the stability of desert ecosystems is facing unprecedented threats and desertification risks becoming increasingly severe. Chinese President Xi Jinping has placed great emphasis on combating desertification, advocating for a comprehensive enhancement of ecosystem stability to strengthen the ecological security barrier in northern China. Therefore, it is imperative to conduct in-depth research on desert ecosystem stability and the processes of desertification.The essence of the desertification issue lies in transitions between different stable states of the system. However, key scientific questions remain insufficiently explored: What stable states do desert ecosystems exhibit along environmental gradients? How do transitions occur between stable states during the desertification process? How can these transitions be predicted and effectively managed? Addressing these challenges demands systematic investigation.
These research findings not only expand the frontiers of understanding desert ecosystem stability and refine the framework of ecological security in desert and desertification-prone areas but also offer critical theoretical support for China's comprehensive desertification control efforts and major national strategies such as the "Three-North" Shelterbelt Project.
