Ecological Aspects of Water Cycle: Advances in Soil Vegetation Atmosphere of Energy and Water Fuxes

针对中国水循环与土壤植物大气水分能量传输生态研究的问题， 进行了综述。阐述了水循环研究的需求与水量转化重要机制， 包括模式与子系统耦合的界面。评述了水、热平衡研究若干工作， 包括农田生态系统， 干旱、半干旱区， 陆面过程模式， 遥感信息的应用以及系统耦合的尺度问题。

This paper dealts with major progresses in China regarding water cycle studies and ecological aspects of Soil Vegetation Atmosphere Transfer (SVAT) in terms of energy and water fluxes. Firstly, the authors of present paper described their views on critical mechanism of water interactions including patterns and interfaces of subsystems′ coupling. Secondly, the authors reviewed some research work on water and energy balance in farmland ecological system, in China′s arid semiarid lands, in terrestrial processes at large scale, in applying remote sensing data to energy fluxes and in resolving scale problems for the coupled systems.
