摘要
以陕西省10个地级市为研究单元,综合运用熵值法、耦合度协调模型、神经网络模型以及GIS技术对陕西省经济发展与生态环境的耦合关系进行了分析,并根据聚类分析结果,将耦合等级分为5个类型,并从总体特征、局域特征两个层面探讨了陕西省10个城市区域经济发展与生态环境耦合的空间格局及其内部差异。结果表明:(1)陕西省的经济发展与生态环境的协调性整体偏低,经济发展与生态环境保护亟待提高;(2)各类型区域的分布具有明显的区位趋同性,且相邻类别区域具有较强的地理邻近性。
The ten districts of Shaanxi Province was selected as the study area. The coupling relationship be tween economic development and ecological environment was analyzed using entropy method, coupling degree model and GIS technology. According to the cluster analysis, the coupling relationship could be divided into five types. The spatial characteristics and internal differences of coupling levels were discussed. Overall, the coupling relationship between economic development and ecological environment in the province was low and needs to be improved. Each level of coupling relationship showed obvious local convergence, and the coupling levels next to each other displayed strong geographic proximity.
