甘肃省主要城市空间扩张协调性分析

Coordination Analysis of Urban Spatial Expansion in Gansu Province

在全国地级以上城市以及典型城市群空间格局监测项目中,根据城市用地增长弹性系数判断城市空间扩展的协调性。结果表明,2000-2016年全国大多数城市用地增长弹性系数大于最优值1.12。分析了城市用地增长弹性系数最优值的来源以及城市空间扩张与人口增长关系的相关研究成果,将人均城市用地面积与城市用地增长弹性系数结合起来,用于城市空间扩张协调性分析,并在甘肃省主要城市进行了空间扩张分析实验。

Based on the data of urban spatial expansion monitoring projects,the urban land of most Chinese cities are expanding too fast judged by the growth ratio of urban land use,which greater than 1.12.In this paper,we analyzed the source of the optimal growth ratio of urban land and the research results on the relationship between urban spatial expansion and population growth,combined the per capita urban land area with the growth ratio of urban land to analyze the coordination of urban spatial expansion,and carried out a spatial expansion analysis experiment in the main cities of Gansu Province.
