鄱阳湖生态经济区生态经济系统耦合研究

以鄱阳湖生态经济区为研究对象,在RS和ArcGIS等软件支持下,基于生态与经济2个子系统构建评价指标体系,采用耦合度与协调度模型分析经济区耦合度和协调度的时空分布特征.研究结果表明:鄱阳湖生态经济区耦合度与协调度总体上呈现北高南低的分布态势.经济区生态经济已由低水平耦合进入拮抗阶段,但2者协调程度仍处于低度协调阶段.经济区生态经济耦合度和协调度分布不均衡,高值区围绕中心城市分布.根据各研究单元耦合度与协调度的组合情况,结合耦合度、协调度理论内涵,可将经济区划分为磨合发展型、经济超前型、拮抗发展型、生态主导型4类区域.研究从主体功能区角度提出促进研究区生态经济协调发展的建议措施.

The Coupling Characteristics of Eco-Economic System in Poyang Lake Eco-Economic Zone

Poyang Lake Eco-economic Zone has been taken as the research object for ecological economic system coupling research.Based on the coupling degree model and coordination degree model,spatial and temporal distribution characteristics of the coupling & coordination degree in Poyang Lake Eco-economic Zone are explored with the help of RS and ArcGIS.The conclusions indicate that:The coupling degree and coordination degree in the Poyang Lake Eco-economic Zone show up imbalance type,it’s higher in the north and lower in the south.The coupling degree of eco-economic system has transformed from a low coupling stage in 2001 into a resisting stage in 2012,however,the coordination degree was still at low level coordination phase.The coupling and coordination degree of eco-economic system are unevenly distributed,high value area gathered around the central city.According to the combination of coupling degree and coordination degree in each research unit,the study area can be further divided into four types of area:amelioration development area,economic advance area,resisting development area and ecological priority area.The researchers put forward some proposals and countermeasures on ecological economic coordinated development from the perspective of major function oriented zone policy.
