| 摘 要： | 从生产力、稳定性、保护性、经济可行性和社会可接受性5个方面选取24个评价因子对鄱阳湖生态经济区土地利用可持续性进行评价,并对其评价指数的时空特征进行研究。研究表明：2007年鄱阳湖生态经济区土地利用可持续性指数为南部高于北部,西南部高于东北部。鄱阳湖生态经济区近7年来的土地利用可持续性指数的总体趋势是逐年上升。鄱阳湖生态经济区土地利用可持续性程度整体上良好,但不同市（县）及不同年份的土地利用可持续性指数存在着明显差异。

| Abstract: | Land use sustainability in Poyang Lake Ecological Economic Zone was examined by 24 evaluating factors in terms of productivity,stability,protection,economic feasibility and social acceptability,and its temporal and spatial features.The results show that relevant indexes in the south are higher than those in the north,and those in the southwest are higher than those in the northeast.Land use sustainable index from 2001 to 2007 was found to be increasing year by year.The condition of the land use stability was sound as a whole while obvious differences exist in different cities and in different years. |
