人口城镇化与土地城镇化协调发展的空间差异研究——以甘肃14个地州市为例

Research on the Spatial Differences of Coordinated Development between Population Urbanization and Land Urbanization——14 Cities in Gansu Province

以甘肃14个地级市为研究区域,建立人口城镇化和土地城镇化发展指标体系,运用耦合协调度模型对2007-2015年甘肃14个地州市人口城镇化与土地城镇化协调发展情况进行分析研究,结果表明:1)14个地州市除兰州外,都属于土地城镇化滞后型;2)对14个地州市人口城镇化与土地城镇化耦合协调发展水平进行分析,金昌、嘉峪关、兰州属于二者协调发展地区;定西、天水、平凉、庆阳、白银、临夏、武威属于过度类地区;张掖、酒泉、陇南、甘南属于失调类地区;3)对14地州市2007年和2015年的二者协调发展程度进行对比分析,发现变化很小.

Taking 14 prefecture-level cities in Gansu as research objects,an evaluation index system for the coordinated development of population urbanization and land urbanization was constructed,and the coordinated development of population urbanization and land urbanization in 14 prefectures in Gansu from 2007 to 2015 was analyzed and studied by the coupling coordination degree model.The results show that:1)except Lanzhou,all the other 13 cities are backward in land urbanization;2)analysis of the coupled and coordinated development level of population urbanization and land urbanization in the 14 cities indicates that Jiayuguan,Jinchang and Lanzhou,are cities where population urbanization and land urbanization develop in a coordinated way;Dingxi,Tianshui,Pingliang,Qingyang,Baiyin,Linxia,and Wuwei are transitional regions;Zhangye,Jiuquan,Weinan and Gannan are areas lacking in coordinated development between population urbanization and land urbanization;3)a comparative analysis of the degree of coordinated development between population urbanization and land urbanization in the 14 cities from 2007 to 2015 shows that the changes are very small.
