陕西省生态-经济-社会综合分区研究

Research on the ecological-economical-social comprehensive regionalization in Shaanxi Province

以多维度多层次理论为基础,应用模糊聚类分析(FCA)和GIS空间分析模型等方法,对陕西省综合分区进行定量研究;针对西北地区生态环境和社会经济发展的特殊问题,建立区划指标体系,应用层次分析法(AHP)确定不同层次指标的权重。应用上述方法,对陕西省95个县市的生态、经济、社会进行综合分区研究,结果得出生态环境区7个,经济社会区9个,综合区13个。通过实地抽样调查表明,上述研究结果能从生态、经济和社会方面准确反映各区的状况,增强了区域可持续发展研究的可操作性,可直接为各区生态环境建设和社会经济的可持续发展提供决策指导。

This paper, based on the theory of multi-dimension and multi-level, establishes the regionalization method using fuzzy clustering analysis and GIS spatial analysis model, and puts forward the mathematical modeling of empirical formula by considering the natural environment characteristics of different zones and main problems, and calculates the index＇s weight in every level using analytic hierarchy process （AHP） method. With above methods the province is environmentally divided into seven areas, economically and socially divide into nine areas, and comprehensively 13 areas. Field survey analysis shows that the results indicate that dividing the areas comprehensively can reflect the reality and is consistent with the investigative sample results, and also shows that the calculated results may guide the practice.
