The measurement of water resources security:A study and challenge on water resources carrying capacity

XIA Jun,ZHU Yi-zhong (Institute of Geographic Sciences and Natural Resources Research,CAS,Beijing100101,China)  
Water resources carrying capacity(WRCC)is a basic measurement of water resources security that plays a very important role in recognizing and building water resources security system.This paper focuses on the WRCC's measurement and quantifying method,which include the usable water resources evaluation,water demand calculation from eco-system and socio-eco-nomic development and the indicator of WRCC and its vector index.As a representative of water conflict in the Northwestern part of China,this paper addresses several key issues related to quantifying WRCC in this region,such as water cycle modeling in the changing environment,water demand problem for eco-system etc.It holds that the hydrological basis related to WRCC,integrated study of natural change and social economics,present practical models and RS/GIS technology,as well as regional variability should be emphasized.
