With the development of the society and economy, the contradictions among population, resources and environment are increasingly worse. As a result, the capacity of resources and environment becomes one of the focal issues for many countries and regions. Through investigating and analyzing the present situation and the existing problems of resources and environment in Poyang Lake Eco-economic Zone, seven factors were chosen as the evaluation criterion layer, namely, land resources, water resources, biological resources, mineral resources, ecological-geological environment, water environment and atmospheric environment. Based on the single factor evaluation results and with the county as the evaluation unit, the comprehensive capacity of resources and environment was evaluated by using the state space method in Poyang Lake Eco-economic Zone. The results showed that it boasted abundant biological resources, quality atmosphere and water environment, and relatively stable geological environment, while restricted by land resource, water resource and mineral resource. Currently, although the comprehensive capacity of the resources and environments in Poyang Lake Eco-economic Zone was not overloaded as a whole, it has been the case in some counties/districts. State space model, with clear indication and high accuracy, could serve as another approach to evaluating comprehensive capacity of regional resources and environment.
随着社会经济的发展，人口、资源与环境之间的矛盾日益加剧。因此，资源与环境承载力成为许多国家和地区关注的焦点问题之一。通过对鄱阳湖生态经济区资源与环境的现状及存在问题进行调查分析，选取了土地资源、水资源、生物资源、矿产资源、生态地质环境、水环境和大气环境7个因素作为评价准则层。基于单因素评价结果，以县为评价单元，运用状态空间法对鄱阳湖生态经济区资源与环境综合承载力进行评价。结果表明，该区域生物资源丰富，大气和水环境质量较好，地质环境相对稳定，但受到土地资源、水资源和矿产资源的制约。目前，鄱阳湖生态经济区资源与环境综合承载力整体虽未超载，但部分县（区）已出现超载情况。状态空间模型具有指示明确、精度较高的特点，可作为评价区域资源与环境综合承载力的另一种方法。
