摘要
以区域可持续发展能力建设为切入点,结合苏北地区的实际,建立适合该地区的可持续发展能力评价指标体系,然后运用SPSS软件的因子分析和聚类分析的方法,对苏北地区可持续发展能力进行综合评价。结果表明,区内各县市可持续发展能力差异较大,但其空间分异呈现出某些特征:经济可持续发展能力呈现由地区东南部向中间递减的“一”字型空间格局;资源环境可持续发展能力呈现由地区中部分别向东、向西递减的“凸”字型空间格局;社会可持续发展能力呈“M”字型空间格局;综合可持续发展能力呈“H”字型空间格局;以中心城市为核心,可持续发展能力向周边呈辐射状递减趋势。根据这些空间分异特征,提出了一些促进苏北地区可持续发展能力建设的建议。
This paper establishes the index system of sustainable development capacity, based on the analysis of the particular background of Northern Jiangsu considering the breakthrough of constructing regional sustainable development capacity, and then evalu- ates the sustainable development capacity of Northern Jiangsu comprehensively by adopting the Factor Analysis Method and Hierarchical Cluster Analysis Method of SPSS. The consequence shows that there are great differentiations of the sustainable development capacity among counties and cities in Northern Jiangsu, but there are some characteristics in regional spatial differentiation of the sustainable development capacity. The sustainable economic development capacity presents the spatial pattern of , higher in the southeast while lower in the middle of Northern Jiangsu. The sustainable resource-environmental development capacity presents the spatial pattern of ＂凸＂, higher in the middle while lower in the east and the west of Northern Jiangsu. The sustainable social development capacity presents the spatial pattern of ＂M＂ and the sustainable comprehensive development capacity presents the spatial pattern of ＂H＂ in Northern Jiangsu. There is a trend of the sustainable development capacity in Northern Jiangsu that it decreases gradually from the middle to the border while taking key city as core. According to these characteristics of spatial differentiation, some suggestions to strengthen the construction of sustainable development capacity in Northern Jiangsu are put forward.
