摘要
水资源承载力是一个国家或地区可持续发展过程中各种自然资源承载力的重要组成部分,对一个国家或地区综合的发展和发展规模有至关重要的影响。由于水资源承载力是涉及到人口、社会经济发展以及资源环境在内的复杂巨系统,通过利用综合多种因素的状态空间法,从综合、宏观的角度来描述研究区域现实的承载状况,并对其进行定量化表示和分析。以贵州省为例,根据其具体情况,选取了9个指标构成评价指标体系,并对各指标运用反映客观赋权的熵值法进行权重的确定,然后通过状态空间法求算出贵州省现实的水资源承载状态值及其理想状态值。计算结果表明,贵州省目前的水资源承载状况总体上处于超载状态,但不同的地区又有所差异,表现出一定的空间地域性。根据贵州省水资源承载的现状值与理想值的比较,把整个贵州省水资源承载力划分为3种类型区:严重超载区、满载区及可载区。计算结果符合贵州省水资源实际情况,对贵州省水资源的可持续利用具有一定的现实指导意义。
Water resources carrying capacity is an important part of all kinds of natural resources of a country or region,and has an important impact on the comprehensive development and development scale of a country or region. Because the water resources carrying capacity is a complex giant system,which is related to population, resources and environment,and socio-economic development,the authors used state space method to describe the realistic carrying situation of the studying area from comprehensive and macro-perspective angle,and represented and analyzed it quantitatively. Taking Guizhou Province as an example,and according to the specific circumstances,9 assessment indexes were selected to constitute the evaluation index system. The weights of the indexes were determined through using the entropy method of reflecting the objective. And then the perfect and realistic states of water resources carrying capacity in Guizhou Province were calculated using state space method. The results showed that the water resources carrying capacity of Guizhou Province is at overloading state at present,and the capacity of water resources carrying demonstrates a certain kind of geographical space feature. According to the comparison of the perfect and realistic state of water resources carrying capacity in Guizhou Province,the province was divided into three types： serious overloading region, full-load region and non-full load region. The calculated results complied with the actual situation of Guizhou Province,and had practical guiding significance for the sustainable use of water resources of Guizhou Province.
