驱动力与制约力相互作用下我国城市空间扩张

Urban Space Expansion in China under the Interaction between the Driving Force and the Restriction

将与城市空间扩张有关的经济社会发展指标按照其对城市空间扩张的作用分为驱动力因素与制约力因素。对36个省会城市和计划单列市2013年数据按照驱动力因素和制约力因素分类后,运用SPSS软件分别进行主成分分析,计算出各城市驱动力与制约力的综合分数。运用散点分析研究出城市空间扩张驱动力综合分数与制约力综合分数,以及其分别与城市建成区面积的关系,寻求驱动力与制约力相互关系最为合理的范围值以及相对应的城市发展空间扩张值。在此基础上,计算各城市驱动力以及制约力分别与Boyce-Clark形状指数计算出来的各城市形状指数之间的关系,分析出最合理的城市空间指数与形状。

The economic and social development index can be divided to driving force factors and restriction factors according to the function to the city space expansion. Classify The data of 36 provincial capital cities and municipalities in 2013, analysis principal component with SPSS software and calculated the urban driving force factors score and restraining factors score. Analyse the relationship between driving force and the city spatial expansion, as well as restriction force. Looking for the most reasonable range between them. On this basis, searching the relationship between the urban driving force and the shape index of calculated by the way of Boyce-Clark.
