On concept, Significance and Strategic Framework for Water Resources Constraint Force
水资源约束力的内涵、研究意义及战略框架

Based on the analysis of the water shortage situation in the process of rapid urbanization throughout the world and China,the concept for Water Resources Constraint Force(WRCF) is presented.It refers to the friction which water resources system gives to the socio-economic system.In other words,when the urban and economic scale approaches to or exceeds the water resources carrying capacity,or the utilization of water resources approaches or exceeds the eco-utmost of natural water resources,water resources system will be highly stressed by socio-economic system.Then water resources system will slow down the socio-economic development.Therefore,the connotation and study significance for WRCF are discussed in detail,and a strategic framework is preliminarily analyzed.It is considered that the strategic framework should mainly include the basic theory,the quantitative method,the case study and the integrated study,and research on WRCF is one of the important contents of water security in the 21st century in the world and China.It aims at resolving the difficult water problems in the real world,and also can enrich the framework and the system info of water resources sciences.Through the study of water resources carrying capacity,water resources stress and WRCF,the interaction and relationship between water resources system and socio-economic system can be exactly explained.At present,the system info of WRCF,including the basic theory,the quantitative method and its case study,should be constructed and perfected.Especially,its birth mechanism,influencing factors,influencing mechanism,variation law and its control should be taken as the key studies.Besides,the integrated study between WRCF and other domains in water resources sciences should also be emphasized.
