中文摘要：

经济和环境的协调发展已经成为区域发展不可忽视的重要问题,鄱阳湖生态经济区作为国家区域发展战略地区之一,其生态与经济的协调发展就显得至关重要.运用DEA方法对鄱阳湖生态经济区36个县（市、区）2009—2013年间氨氮排放效率及其变化率进行分析.结果显示：各县（市、区）之间氨氮排放效率差异明显,东湖区、西湖区、青云谱区和渝水区等8个县（市、区）氨氮排放效率较高,其他县（市、区）氨氮排放效率中等或低下.Malmquist生产率指数计算显示除了南昌县、余江县、高安市和万年县4个县（市、区）氨氮排放综合效率降低外其余都有所上升或不变.依据主导产业和氨氮排放效率将鄱阳湖生态经济区36个县（市、区）划分为高效率第二产业主导区、中效率第二产业主导区、低效率第二产业主导区等8类区域,并提出产业结构调整的相关建议.

英文摘要：

The harmonious development of economy and environment has become an important problem that cannot be ignored in the regional development.As one of the national regional development strategy,Poyang Lake eco-economic zone is crucial to the coordinated development of ecology and economy.The efficiency and variation of ammonia nitrogen emissions of 36 counties（cities/districts） in the Poyang Lake eco-economic zone from 2009 to 2013 were carried out with data envelopment analysis（DEA） method.The results showed that there were obvious differences for the ammonia nitrogen emissions efficiency among the counties（cities/districts）,thereinto,the ammonia nitrogen emissions efficiency in the eight counties（cities/districts）（e.g.Donghu,Xihu,Qingyunpu,and Yushui,etc.） was higher,and was medium or low in other counties（cities/districts）.Except for Nanchang,Yujiang,Gaoan and Wannian,the comprehensive efficiency of ammonia nitrogen emissions increased or unchanged in other counties（cities/districts） based on Malmquist productivity index.The 36 counties（cities/districts） in the Poyang Lake ecoeconomic zone were divided into 8 categories according to dominant industry and ammonia nitrogen emissions efficiency,such as high efficiency of ammonia nitrogen emissions in the dominant regions of secondary industry,medium efficiency of ammonia nitrogen emissions in the dominant regions of secondary industry,and low efficiency of ammonia nitrogen emissions in the dominant regions of secondary industry,and so on.In addition,the related suggestions of industrial structure adjustment were put forward.
