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。 The coordinated development level between intensive land use and new urbanization of agglomeration is the core issue in land management.The coordinated development level of middle Yangtze River Region and Chengdu—Chongqing urban agglomeration,which are the urban agglomerations in middle and upper reaches of the Yangtze River,was analyzed to provide some relevant references.Generalization Principal Component Analysis and Mean-Squared Deviation Weight were used to improve the accuracy of the index weight.We used coupling degree model and coordinated development degree model to measure,analyze,compare the coordinated development level of the middle Yangtze River region and Chengdu—Chongqing urban agglomeration.Spatial Autocorrelation Model was used to explore the characteristics and rules of spatial agglomeration of coordinated development level.The results show that the coordinated development level in Chengdu—Chongqing urban agglomeration is close with the middle Yangtze River Region.The coupling coordinated situation in Chengdu—Chongqing urban agglomeration is better than the middle Yangtze River Region.(1)The coordinated development level of the urban agglomerations in middle and upper reaches of the Yangtze River is showing the trend of sustained growth.The coordination degree between the middle Yangtze River Region and Chengdu—Chongqing urban agglomeration is very close in 2013,its value is greater than 0.75 and the coordination development level is in moderate coordination period.Chengdu,Chongqing,Changsha,Wuhan,Nanchang are the areas with high value of coordinated development.Deyang and Huangshi are areas with the low value of coordinated development.The coordinated development levels in other cities are characterized as the medium level.(2)The spatial correlation of coordinated development degree is reduced in the middle Yangtze River Region,transforming from random distribution to weak diversity attribute clustering.The spatial correlation of coordinated development degree is relatively high in C
