摘要
为了合理地对鄱阳湖域生态经济区进行区划,构建了包括经济发展、社会建设、资源保障和环境保护的鄱阳湖域生态经济区划指标体系,运用粗糙集理论的属性约简筛选出评价指标,利用融合信息熵计算指标重要度,结合突变级数模型计算鄱阳湖域32个区划单元的生态经济综合量化值。根据各区划单元的生态经济综合值,通过模糊聚类方法,将区划单元按生态经济系统状态区划为优、良、中、一般、差5个等级。区划结果表明,研究区域呈现"橄榄型"分布,区划结果较为合理,可为将鄱阳湖域建设成为全国生态文明示范区和中国低碳经济发展先行区提供决策参考。
To reasonably implement the eco -economic zoning of Poyang Lake area, an evaluation index system consisting of four criteria such as economic development, social construction, resources safety and environmental protection is constructed ; the attribute reduction of rough sets is used to filter the indexes of evaluation and the fused information entropy is adopted to calculate the importance of indicators; the catastrophe progression model is applied to calculate comprehensive quantitative values of 32 division units of Poyang Lake Zone. According to comprehensive eco - economic evaluation values of various zoning units, by using fussy cluster method, the zoning units are divided into five grades of excellent, good, medium, general and poor. The zoning results show that the research area is in an olive distribution and the zoning is reasonable, which could provide decision -making reference for the construction of national ecological civilization demonstration area and national low - carbon economical development pilot area.
