城市土地集约利用与社会经济时空耦合协调发展评价——以湖北省12个地级市为例

Spatiotemporal Development and Coupling Relationship of Urban Intensive Land Use and Social Economics——A Case Study of 12 Cities in Hubei Province

土地集约利用与社会经济发展的耦合协调发展可有效推动城市的可持续发展。首先运用主成分分析法对湖北省12个地级市的土地集约利用与社会经济发展水平进行了评价,在此基础上运用耦合协调度模型对两者之间的协调度进行了分析。结果显示:2003—2013年,湖北省12个主要城市间土地集约利用水平、社会经济发展水平差异较大,且差距总体呈逐年递增态势。其中,武汉、黄石、十堰、宜昌4个城市优势明显,处在平均水平以上,其他8个城市发展较为缓慢。从时空耦合发展状况来看,研究期内湖北省12个城市之间的耦合协调性地域带动性不强,城市的耦合协调性受相邻城市的影响不大;局部分析上,黄冈、鄂州、咸宁、孝感4个城市有明显高值极化分布,耦合协调度高但是没能带动周围城市的发展;武汉市耦合协调度较低,发展速度明显没有跟上周围城市的发展,有待提高。

The coordinated development of urban intensive land utilization and social economic development can effectively promote sustainable development of city. The paper evaluates the level of urban intensive land use and social economic development by the method of principal component analysis （PCA）. Then, 12 cities of Hubei Province from 2003 to 2013 were taken as the examples, the coordinated degree between urban land intensive use and social economic development is analyzed. The results show that wide difference of the level of intensive land use and economic development among the 12 major cities in Hubei Province and the gap were increasing year by year as a whole. Among them, four cities such as Wuhan, Huangshi, Shiyan, and Yichang have obvious advantages, and are at the average level of the above, the other eight cities are relatively slow development. In the aspect of spatiotemporal coupling development status, the regional drive of coupling coordination among the 12 cities of Hubei Province is not strong in the study period, and the coupling coordi- nation of cities is not affected by the neighboring cities. On the aspect of local analysis, four cities such as Huanggang, Ezhou, Xianning, Xiaogan have significantly higher value polarization distribution. The coupling coordination degrees of the four cities are high but fail to drive the developments of surrounding cities; the coupling coordination degree of Wuhan City is relatively low, and the development speed does not obviously kept UP with the surrounding cities, which needs to be improved.
