生态脆弱能源区人居环境与经济协调发展时空格局及演化机制——以晋陕蒙接壤区为例

以晋陕蒙接壤区为例，运用综合指数法、协调发展度模型和PCA模型方法，构建协调发展变化模型，借助GIS和SPSS技术，研究2000-2015年生态脆弱能源区人居环境与经济协调发展时空特征，揭示人居环境与经济系统时空协调演进机制。结果表明：2000年以来，晋陕蒙接壤区人居环境与经济系统协调发展度长期处于勉强协调发展类型；县域人居环境与经济系统协调发展度由“北高南低”演化为“中部高周边低”的空间分异特征；榆阳区、府谷县、横山县、神木县、东胜区、准格尔旗、伊金霍洛旗的人居环境与经济系统协调发展度显著提升，河曲县、保德县、偏关县、兴县、达拉特旗和托克托县的协调发展度出现下降态势；人居环境与经济系统时空协调演进是居住环境因子、产业结构因子、基础设施因子、公共服务设施因子和政府宏观政策调控因子等多重动力因子综合驱动的结果。据此提出推进区域人居环境与经济系统向优质协调发展类型演进的对策建议。

Spatial-temporal pattern and evolution mechanism of coordinated development of human settlement environment and economy in energy accumulation and vulnerable ecology regions:A case of contiguous areas among Shanxi-Shaanxi-Inner Mongolia

As the important bases and carriers of national ecologic and energy security,energy regions and play a prominent role in the national economic development,and the coordinated development between the human settlement environment and the economy is closely related to the socio-economic sustainable development and the vital interests of the people in this region. Therefore,the research on the spatial-temporal pattern and evolution mechanism of the coordinated development between the human settlement environment and economy in theses regions is of great theoretical and practical significance,it not only can help the study of regional geography and also promote the coordinated development between human settlement and economy in the energy regions and vulnerable ecology regions. Taking the contiguous areas of Shanxi-Shaanxi-Inner Mongolia as the study area,this paper analyzes the spatial-temporal pattern characteristics of the coordinated development between human settlement environment and economy system,and reveals its driving mechanism from 2000 to 2015 in 13 counties of the contiguous areas among Shanxi-Shaanxi-Inner Mongolia,based on the GIS and SPSS,the methods of comprehensive index,the coordinated development degree,PCA (Principal Component Analysis),by building the variation model of the coordinated development. The results show that: From 2000 to 2015,the human settlement environment and economy system are in an uncoordinated state,and the spatial differentiation has shifted from the pattern which is higher in the north areas while lower in the south to the pattern which is higher in the central areas while lower in the periphery. The degree of the coordinated development of Yuyang,Fugu,Hengshan,Shenmu, Dongsheng,Zhungeer and Yijinhuoluo has been significantly improved. However,the degree of the coordinated development of Hequ,Baode,Pianguan,Xingxian,Dalad banner and Togtoh is on a decline. Living environment conditions,industrial structures,infrastructure and public service facilities,and government macroeconomic regulations and control policies were the main driving forces for the coordinated development between human settlement environment and economy. Among them,the primary driving force for the coordinated development between human settlement environment and economy is the living environment conditions,followed by the transformation and upgrading of industrial structure. Meanwhile,the improvement of infrastructure and public service facilities is an important factor,and the government macroeconomic regulations and control policies plays a prominent role in the coordinated development between human settlement and the economy. In order to realize the coordinated development between the human settlement environment and economy,improving living conditions and the infrastructure and public services,promoting the transformation and upgrading of industrial structure, establishing ecological energy economy zones and the macro-control policies are needed.
