由于我国城市群区域发展差异显著,国土综合整治需分类有序推进。立足于地域系统理论采用熵值法、关联性分析等方法,从建设用地投入、利用强度、产出水平、利用品质等维度构建了度量城市群国土空间综合利用效率的指标体系和计量模型,划分了国土综合利用效率分区,从国土综合整治角度明确了整治路径。结果 表明:我国城市群综合发展指数区域差异显著,呈现东部沿海高,中西部地区低的区域特征; 全国城市群空间利用综合效率可以划分为3个综合指数区和12个整治提升区,不同类型区特点鲜明,城市群分区的差异是资源禀赋、地理区位、政策制度倾向、产业结构等众因素交叉作用的综合体现。通过对城市群国土空间利用效率的特征及分异机制的研究,不仅为国土空间综合整治途径提供了理论基础,并且能为国土空间规划服务。

Due to the significant differences in the regional development of urban agglomerations in China, the comprehensive improvement of land needs to be carried out in an orderly and classified manner. Based on the theory of regional system, we used entropy method, correlation analysis, radar chart and other methods to construct the index system and measurement model to measure the comprehensive utilization efficiency of urban agglomeration's land space from the dimensions of construction land input, utilization intensity, output level, utilization quality, etc., divide the zones of comprehensive utilization efficiency of land, and define the remediation path from the perspective of comprehensive remediation of land. The results show that there are significant regional differences in the comprehensive development indices of urban agglomerations in China, showing the regional characteristics of high level in the eastern coast and low level in the central and western regions; the comprehensive efficiency of spatial utilization of urban agglomerations in China can be divided into 3 comprehensive index areas and 12 improvement areas; different types of areas have distinct characteristics; the differences of urban agglomerations are the comprehensive reflection of the cross-effects of many factors such as resource endowment, geographical location, policy and system tendency, industrial structure, etc. This study on the characteristics and differentiation mechanism of the land space utilization efficiency of urban agglomeration not only provides the theoretical basis for the comprehensive improvement of land space, but also serves the land space planning.
