中文摘要：

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．

英文摘要：

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 envi- ronment 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 environ- ment, 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.
