水资源承载力研究进展与新方法

PROGRESS AND A REVIEW OF NEW METHODS IN WATER RESOURCES CAPACITY RESEARCH

在综述水资源承载力前人研究的基础上,总结了水资源承载力研究中存在的问题:水资源承载力的概念不明确;水资源承载力的量化方法建立在概念不一致的基础之上,导致水资源承载力量化可操作性差;当前水资源承载力的研究没有完全符合可持续发展思想等.为解决这些问题,本文提出了水资源承载力的新定义及相关的量化方法:水资源承载水平是在一定的技术和管理水平下,区域水资源系统承载的人类发展水平;水资源承载力是水资源承载水平的稳定最大值,即一定的技术和管理水平下,区域水资源系统能稳定承载的人类最大发展水平;并以生态服务功能价值为标尺,从经济、文化、生态支撑、生态同化4个方面建立水资源承载力的量化方程.

To better guide economic and social development planning, to rationally develop water resources,and to promote sustainable human development,water resources carrying capacity （WRCC）has been researched in-depth.Major problems in water resources carrying capacity were summarized as follows. The concept of WRCC is not clear;Quantitative methods were confused due to inconsistent concepts of WRCC, resulting in poor operability of WRCC;WRCC study is,to some degree,incongruous with the concept of sustainable development.To solve these problems,a new definition of WRCC and related quantitative methods are proposed in this paper.The water resources carrying level （WRCL）should refer to human development level,under certain circumstance of technology and management,held by regional water resources system;WRCC is stable maximum of WRCL,maximum of human development level steadily caught by regional water resources system,under certain level of technology and management;WRCC quantitative equation is,scaled by ecosystem services value, established from 4 aspects including economy, culture, ecological support and ecological assimilation.
