水资源承载力是衡量水资源安全的基本指标，对认识和构建水资源安全体系具有十分重要的作用。本文重点研究了水资源承载力的测量和量化方法，包括可用水资源评价、生态系统和社会经济发展的需水量计算、水资源承载力指标及其向量指数。本文以西北地区水冲突为代表，阐述了变化环境下的水循环模型、生态系统需水问题等水资源承载力量化的关键问题，认为应重视水资源承载力的水文基础、自然变化与社会经济学的综合研究、现有实用模型与RS/GIS技术以及区域变异。
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.
