重庆市城镇化进程中城市土地集约利用研究

Research on urban land intensive use in the process of urbanization in Chongqing

以重庆市为例,采用主成分分析法,对重庆市2006—2015年城镇化进程中的城市土地集约状况进行综合评价分析;通过构建协调度模型,对重庆市城镇化水平与土地集约利用耦合协调度进行测度。结果表明:重庆市的整体协调度主要处于拮抗状态且呈波浪起伏状,其协调发展仍需进一步提升;重庆市城镇化与城市土地集约利用的协调发展具有动态性,其动态协调度的高低取决于城镇化发展与城市土地集约利用水平的高低;重庆市城镇化与城市土地集约利用的协调度主要受到城市土地投入强度与经济城镇化的影响。

Taking Chongqing as an example,a principal component analysis method was used to conduct a comprehensive evaluation and analysis of the urban land intensive use during the urbanization process in Chongqing from 2006 to 2015.By constructing a coordination degree model,the degree of coordination between urbanization evolution and land intensive use is measured.The results show that the coordination degree in Chongqing is mainly in an antagonistic state and shows an undulating state,and its coordinated development still needs further improvement;the coordinated development of urbanization and urban land intensive use in Chongqing is dynamic.The degree of dynamic coordination depends on whether the development of urbanization is in line with the level of urban land intensive use;the degree of coordination between urbanization and urban land intensive use in Chongqing is mainly affected by urban land input intensity and economic urbanization.
