Title: Research on the Snow-Vegetation-Hydrology-Society Cascade Effects
Reporter: Dr. Guo Hui, North China University of Water Resources and Electric Power
Time: 10:00-12:00, November 17, 2025 (Monday)
Venue: Meeting Room 1408, Guanyun Building, Chengguan Campus, Lanzhou University
Moderator: Prof. Zhang Baoqing, School of Earth and Environmental Sciences, Lanzhou University
Reporter Profile:
Guo Hui is a young faculty member and master's supervisor at North China University of Water Resources and Electric Power. His main research focuses on the snow-vegetation-hydrology-society cascade effects. In recent years, he has published 14 SCI papers as the first or corresponding author in journals such as Journal of Hydrology, Agricultural and Forest Meteorology, and Science China Earth Sciences. Additionally, he has co-authored more than 20 SCI papers in internationally renowned journals, including Nature Reviews Earth & Environment, Nature Communications, and Global Change Biology. He currently leads or participates in several national and provincial research projects, including Young Scientists Fund Program of the National Natural Science Foundation of China (NSFC) and Young Scientists Project Grant of the National Key R&D Program. He also serves as a reviewer for journals such as Journal of Hydrology and Climate Dynamics.
Report Abstract:
Under the combined influence of climate warming and human activities, snow evolution, vegetation dynamics, hydrological processes, and water-use regulation in cold regions are closely coupled, forming a "snow-vegetation-hydrology-society"cascade chain. Disturbances in snow accumulation and melt timing in alpine headwaters alter spring soil moisture and river recharge, thereby reshaping the seasonal distribution of downstream water resources. Meanwhile, large-scale greening and earlier vegetation phenology enhance evapotranspiration during the growing season, producing a pronounced "ecological water consumption" effect that further impacts the spatial-temporal balance of downstream water and soil resources. Such cascading responses have been observed and simulated in typical river basins across China; however, the identification of key mechanisms, quantitative coupling assessments, and the development of operational indicators for governance remain insufficient. This report focuses on these cascade effects, systematically elaborating on snow variation and its attribution, snow-albedo feedback mechanisms, and the impacts of snow changes on vegetation and their underlying processes, providing methodological and empirical support for optimizing regional water-soil resource allocation and guiding management decisions.
