| 摘 要： | 运用耕地压力指数扩展模型,分析2000—2009年鄱阳湖生态经济区耕地压力时空差异及其规律。结果表明:2000—2009年鄱阳湖经济生态区总体耕地压力并未超过预警线,但鄱阳湖生态经济区各县耕地压力不平衡,鄱阳湖生态经济区东南区域和西北区域耕地压力明显大于其他区域。并针对鄱阳湖生态经济区耕地压力状况提出相应对策和建议。

| Abstract: | Use of arable land pressure model,this paper analyzed the spatial and temporal differences of cultivated land pressure in Poyang Lake Ecological Economic Zone from 2000 to 2009.The results showed that arable land pressure did not exceed the warning line,however,the county farmland pressure was unbalanced.Arable land pressure in the southeast region and northwest region of Poyang Lake Ecological Economic Zone were significantly greater than those in other regions.The corresponding countermeasures and suggestions were put forward. |
