城市土地集约利用度与城市化水平协调发展研究——以武汉城市圈为例

以武汉城市圈为例,建立城市土地集约利用及城市化水平评价指标体系,采用全局主成分分析法评价2005~2014年土地集约利用度与城市化水平,运用系统相对状态发展模型测算两者之间的协调度,并对其进行时空维度上的差异分析。协调度测算结果显示,2008年以后圈内各市多处于协调阶段;从时间轴上看,武汉、黄石、孝感、潜江市的土地集约利用与城市化水平协调度总体趋于逐年增强,但在空间格局上各市呈现不规则变化态势,不具有明显的空间聚集特征。

Research on the Coordination Coefficient of the Intensiveness of Urban Land Use and Urbanization——A Case of Wuhan Urban Agglomeration

Taking Wuhan Urban Agglomeration as an example,set up evaluation systems of the urban land intensive use and urbanization level. The global principal component analysis (GPCA) and the model of system's relative state development de-gree has adopted. GPCA is used to evaluate urban land intensive use and urbanization level from 2005 to 2014. And the model of system's relative state development degree is used to measure the coordination degree between the two,finally ana-lyze the change characteristics in the time and space dimensions. The results declare that the cities in Wuhan Urban Ag-glomeration whose most period after 2008 is in coordination stage. Looking from the time axis, the coordination coefficient of the intensiveness of urban land use and urbanization in Wuhan,Huangshi,Xiaogan,Qianjiang generally tends to increase year by year. However,it's obvious that cities' coordination coefficient trend an irregular change and is without obvious character-istics of spatial clusters.
