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。
運用耕地壓力指數擴展模型，分析2000-2009年鄱暘湖生態經濟區耕地壓力時空差異及其規律。結果錶明：2000-2009年鄱暘湖經濟生態區總體耕地壓力併未超過預警線，但鄱暘湖生態經濟區各縣耕地壓力不平衡，鄱暘湖生態經濟區東南區域和西北區域耕地壓力明顯大于其他區域。併針對鄱暘湖生態經濟區耕地壓力狀況提齣相應對策和建議。

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.
