【摘要】：城市群土地集约利用与新型城镇化耦合协调发展是土地管理学研究的核心问题,探讨长江中上游城市群——长江中游和成渝城市群的耦合协调发展水平,以期为中国其他城市群的相关研究提供参考。利用全局主成分分析法、均方差权值法、熵权法进行综合确权以提高评价指标权重精度,采用耦合度模型、协调发展度模型对长江中游和成渝城市群协调发展水平进行了测算、分析与比较,进而利用空间自相关模型探究各城市群土地集约利用与城镇化协调发展水平的空间集聚特征与规律。结果表明:成渝城市群土地集约利用与新型城镇化协调发展水平与长江中游相当,成渝城市群耦合协调态势优于长江中游城市群。具体体现在(1)2004—2013年长江中上游城市群土地集约利用与新型城镇化协调发展水平呈现出持续递增的态势,2013年长江中游和成渝协调发展度相近,均在0.75以上,处于中度协调期,成都、重庆、长沙、武汉、南昌等城市为协调度高值区,德阳、黄石为协调度低值区,其他城市的协调发展水平居中。(2)长江中游协调发展度空间相关性有所降低,由随机分布向弱相异属性集聚转化,而成渝协调发展度空间相关性有所提升,由相异属性集聚向随机分布状态转化,未来有逐步优化为相似属性集聚的态势。
[Abstract]:The coupled and coordinated development of intensive land use and new urbanization in urban agglomeration is the core of land management research. This paper probes into the level of coupled and coordinated development of urban agglomeration in the middle and upper reaches of the Yangtze River and Chengdu-Chongqing urban agglomeration. In order to provide a reference for other urban agglomeration research in China. Using global principal component analysis method, mean square error weight method, entropy weight method to improve the accuracy of evaluation index weight, using coupling model. The coordinated development level of the middle reaches of Yangtze River and Chengdu-Chongqing urban agglomeration is calculated, analyzed and compared with the model of coordinated development degree. Then the spatial agglomeration characteristics and laws of the coordinated development level of land intensive utilization and urbanization in various urban agglomerations are explored by using spatial autocorrelation model. The coordinated development level between intensive land use and new urbanization in Chengdu-Chongqing urban agglomeration is similar to that in the middle reaches of the Yangtze River. The coupling and coordination situation of Chengdu-Chongqing urban agglomeration is superior to that of the middle Yangtze River urban agglomeration. From 2004 to 2013, the coordinated development level of urban agglomeration land use and new urbanization in the upper and middle reaches of the Yangtze River showed a situation of increasing. In 2013, the coordinated development of the middle reaches of Yangtze River and Chengdu-Chongqing is similar, both of them are above 0.75, in the moderate coordination period, Chengdu, Chongqing, Changsha, Wuhan, Nanchang and other cities are the high-value areas of coordination, Deyang. Yellowstone is the low value area of coordination degree, and the level of coordinated development of other cities is in the middle. 2) the spatial correlation of coordinated development degree in the middle reaches of the Yangtze River has been reduced, which is transformed from random distribution to weak dissimilar attribute agglomeration. The spatial correlation of the degree of coordinated development of Chengdu-Chongqing has been improved from the different attribute agglomeration to the random distribution state and there will be a situation of gradual optimization to similar attribute agglomeration in the future.
