干旱区流域水文-生态过程耦合分析与模拟研究框架

Discussion of Research Framework of Coupled Analysis and Simulation of Hydro-ecological Processes in Arid Watersheds

干旱区流域水资源短缺与生态恶化问题日趋严重,水文-生态过程耦合分析与模拟问题是实现干旱区流域水安全与生态安全亟待解决的核心科学问题。在总结国内外水文-生态过程耦合研究现状的基础上,探讨当前干旱区流域水文-生态过程耦合研究面临的关键科学问题,初步提出干旱区流域水文-生态过程耦合研究框架,包括水文-生态过程的作用机制、耦合关系和耦合模拟研究,旨在为干旱区流域水文-生态耦合研究提供参考。

The shortage of water resources and the deterioration of ecosystem have become increasingly serious in the arid water sheds. Coupled analysis and simulation of the hydroecological processes are believed to be a core science to realize the water and ecological safety in the arid watersheds. This paper summarized the current worldwide research progress of the hydroecological processes, discussed the key scientific problems in the hydroecological processes at present, and proposed the research frame work for the coupled analysis of the hydroecological processes in the arid watersheds, including the mechanism, coupled rela tionship and simulation of the hydroecological process. This framework can provide references for the research of coupled hydroecological processes in the arid watersheds.
