摘　　要：通过离心模型与贡献度测算,对长江中游城市群31个城市工业用地演变历程及其时空特征进行研究,结果如下:(1)1990-2019年期间,长江中游城市群的工业用地总增幅达300%,经历了启动、加速、高峰三个增长阶段。其占建成区增量的比重达到41.08%,是带动城市群发展的主要力量。(2)武汉城市圈、长株潭城市群、南昌都市圈对工业用地的集聚作用不断加强,在2019年已集中了整个城市群55.96%的工业用地,而其他城市工业用地增长相对滞后,导致长江中游城市群工业用地布局呈现显著的不均衡性。(3)城市规模与工业用地对城市扩张的贡献度成强正相关,说明工业用地增长是促进城市规模提升的主要因素。(4)三大城市圈中工业用地分布过度集中,且靠近长江、洞庭湖、鄱阳湖等重要生态区。如果保持现有增速,很可能因超过区域环境承载力而带来严重的生态问题。The methods of centrifugal model and contribution measurement are used to analyze the evolution characteristics of the urban agglomerations in the middle reaches of the Yangtze River(UAMRYR). Results show that: 1)The total growth of industrial land in the UAMRYR reached 300%,and experienced three growth stages which were startup,acceleration and peak in 1990-2019. The industrial land accounts for 41.08% of the increment of the built-up areas,which was the main driving force for the development of the UAMRYR. 2) The concentrating effect on industrial land of the Wuhan metropolitan area,the Changsha-Zhuzhou-Xiangtan urban agglomeration and the Nanchang metropolitan area strengthened constantly. In 2019,they centralized 55.96% industrial lands of whole UAMRYR,meanwhile the industrial land increasing in other cities were lagging relatively, which leaded to an obvious spatial imbalance of industrial land distribution in the UAMRYR. 3) There was a strong positive correlation between the city size and the contribution of industrial land to urban expansion,which indicated that the growth of industrial land was the main factor to promote the urban expansion. 4) The distribution of industrial land in the three metropolitan areas was excessively concentrated and close to the important ecological areas such as Yangtze River,Dongting Lake and Poyang Lake. If the current growth rate is maintained, it is likely to cause serious ecological problems due to exceeding the regional environmental carrying capacity.
