中国城市群土地利用互补性比较研究——以14个城市群为例

互补性指基于区域间禀赋差异,借助“流”要素促进区域间优势互补,使得总体效益大于个体之和。从互补性概念出发,以中国14个城市群为案例研究区,借助SPSS对应分析及ArcGIS平台,结合能够反映互补性的统计量指标总惯量,对中国城市群土地利用互补性进行时空分析。结果表明：① 中国城市群土地利用互补性差异较大,以长江经济带为轴,向北向南土地利用互补性增加;② 中国超大型城市群城市用地类型综合化特征显著,土地利用互补性低于全国重要地区城市群;③ 大多数城市群5年间互补性呈现下降趋势,城市间产业同构,缺乏特色。未来在合理的城市群规划基础上,加快相关民生政策跨行政区合作,打破行政壁垒,协调区域间土地供求关系,明确城市功能定位,形成协调互补的城市发展格局。

Comparative study on land use complementarity of China: Taking 14 urban agglomerations as an example

Complementarity is based on interregional endowment differences, which promotes regional advantages by virtue of flow factors. The complementarity of land use is the basis of complementarity of city functions, and the reasonable division of labor in urban agglomeration makes the overall benefit greater than the sum of the parts. This paper starts from the concept of complementarity, taking 14 agglomerations in China as case study areas. Firstly, we perfect the connotation of the complementary. Secondly, with the aid of correspondence analysis of SPSS and ArcGIS platforms, combining complementary statistic index of total inertia, this paper analyzed land use complementary of urban agglomerations in China on space-time dimensions. Results show that the complementary of land use differences between agglomerations, urban agglomerations along the Yangtze River Economic Belt presents a pattern of latitude distribution. The comprehensive characteristics of urban land use types in China's super large urban agglomerations are significant, but the level of land use complementarity between these cities is mostly lower than that in China's important regional urban agglomerations. The complementarity of most urban agglomerations has declined in five years. Industrial structure is similar between cities, and lack of unique characteristics. In the future, we should coordinate the land supply and demand relationship between regions, accelerate the cooperation of relevant people's livelihood policies across administrative regions and break down administrative barriers, so as to promote the overall development of urban and rural areas, and form a coordinated and complementary development pattern between cities.
