摘　　要：选取鄱阳湖生态经济区城市综合承载力评价研究的19个指标。利用熵值法计算指标权重系数,构建城市综合承载力评价的物元模型,把整个区域划分为承载力强、较强、中等、弱4个等级。结果表明:城市综合承载力强的城市有6个,较强的城市有13个,中等的城市有9个,弱的城市有4个,鄱阳湖生态经济区城市综合承载力水平总体良好,有较大的发展空间,并且承载力水平呈现出城市中心向周边地区递减的现象。The study select 19 indexes of the urban comprehensive capacity evaluation of Poyang lake ecological economic zone. Using entropy method to calculate index weight, and to establish the urban comprehensive capacity evaluation on matter-element model, then the whole area is divided into four grades：Strong, strong, medium, weak. The results show that the strong capacity cities have 6, the strong capacity cities have 13, the medium capacity cities have 9, the weak capacity cities have 4. The urban comprehensive capacity of Poyang lake ecological economic zone overall good, the cities have a larger development space,and the cities capacity presents phenomenon that center cities decline to surrounding cities.
