【摘要】：随着社会经济的发展,人口、资源与环境之间的矛盾日趋加剧.因此,资源环境承载力问题成为各国(地区)政府所关注的焦点问题之一.本文通过对鄱阳湖生态经济区内资源、环境的现状及问题进行调查分析,选取土地资源、水资源、生物资源、矿产资源、生态-地质环境、水环境及大气环境作为评价准则层,在对上述7个单因素进行评价基础之上,以县(市、区)为评价单位,采用状态空间法对全区的资源环境承载力进行综合评价.结果表明:当前全区内生物资源较丰富,大气、水环境质量良好,地质环境整体较稳定,制约因素主要为土地资源、水资源和矿产资源;全区资源环境承载力表现为可载状态,但部分县(市、区)表现为超载状态.利用状态空间法进行区域资源环境综合承载力研究是可行的,具有意义明确、评价精度高等优点,可为区域资源环境综合承载力评价提供另一种途径.
[Abstract]:With the development of social economy, the contradiction between population, resources and environment is becoming more and more serious. Therefore, the issue of carrying capacity of resources and environment has become one of the focal issues concerned by the governments of various countries (regions). By investigating and analyzing the present situation and problems of resources and environment in Poyang Lake Ecological Economic Zone, this paper selects land resources, water resources, biological resources, mineral resources, eco-geological environment, water environment and atmospheric environment as the criteria for evaluation. On the basis of the evaluation of the seven single factors mentioned above, the comprehensive evaluation of the carrying capacity of resources and environment of the whole region is carried out by using the state space method, taking the county (city, district) as the evaluation unit. The results show that the biological resources in the whole area are abundant, the quality of atmosphere and water environment is good, the geological environment is stable, and the restrictive factors are mainly land resources, water resources and mineral resources. The carrying capacity of resources and environment in the whole region is loadable, but in some counties (cities and districts) it is overloaded. It is feasible to study the comprehensive carrying capacity of regional resources and environment by using the state space method, which has the advantages of clear meaning and high evaluation precision. It can provide another way for the comprehensive carrying capacity evaluation of regional resources and environment.
