中国城市群土地承压施压耦合曲线的时空特征

Spatiotemporal Characteristics of Land Pressure-bearing and Pressure-applying Coupling Curves of China’s Urban Agglomerations

文章从承压施压角度定义土地承载力并借助承压施压耦合曲线确定土地承载力分区标准,对中国城市群2006—2017年土地承载力的时空演变特征进行分析。研究结果表明:城市群城市土地承载力分区基本处于超载低值区、平衡区、盈余低值区;从时空演变角度对土地承载力分区状况进行分析,2006—2017年东部城市群中处于盈余低值区的城市较多,其次是中部城市群,西部城市群中处于盈余低值区的城市较少。

This paper defines the land bearing capacity from the perspective of pressure-bearing and pressure-applying,and determines the partition standard of the land bearing capacity by pressure-bearing and pressure-applying coupling curves,and then analyzes the spatiotemporal evolution characteristics of land bearing capacity of China’s urban agglomerations from 2006 to2017.The results show that the urban land bearing capacity partition of urban agglomerations is basically in the range of overloaded low-value area,equilibrium area and surplus low-value area,and that based on the analysis of land bearing capacity partition in terms of spatiotemporal evolution,more cities of the eastern urban agglomerations are in the surplus low-value area,followed by the central urban agglomerations,and fewer cities of the western urban agglomerations from 2006 to 2017 are in the surplus low-value area.
