区域空间结构演变多尺度研究——以鄱阳湖生态经济区为例

从不同的尺度结合外贸依存度、首位城市度、城市联系强度、聚类分析和分形理论,对环鄱阳湖生态经济圈的空间结构及其相互作用的演变进行分析,发现环鄱阳湖经济圈进出口额和外贸依存度逐年上升,但仍与发达城市群差距明显;城市体系不够完善,中小城市发达缺乏大城市,产业结构不合理需要整合优化;各市县经济联系强度差异明显,针对各市县经济联系的层次性可实施统一协调和梯次发展战略。

Poyang Lake Ecological Economic Circle of Multi-Scale Spatial Structure Evolution

Poyang Lake ecosystem spatial structure of economic circle analysis of the evolution and interaction was performed.We found that the Poyang Lake economic circle of dependence on foreign trade import and export volume increased year by year,but still significant gap between the developed urban agglomeration;urban system was not perfect enough,the lack of large cities.medium and small cities developed,three irrational industries structure need to integrate;the Economic Relation Intensity of cities and counties significant for the level of economic ties We can implement a coordinated and Echelon development strategy.
