摘　　要：应用城市拓展的资源消耗响应程度模型,深入分析2000—2012年江苏省城市拓展与资源消耗关系的时空格局特征。研究发现:(1)城市拓展与资源消耗呈同步增长趋势,且二者的区域差异均呈现缩小之势;(2)城市拓展与资源消耗整体上处于相对脱钩状态,且脱钩程度不断增强,各城市演化方向趋异;城市拓展对资源消耗影响程度呈增强态势,不同类型城市分异显著;(3)城市拓展是导致其资源影响程度提高的主要动力,促进城市集约增长是破解城市拓展与资源消耗矛盾的路径选择。By using the decoupling state model and response degree mode, the spatio-temporal evolution of the influence of urban expansion on the resource consumption was deeply explored based on the statistic data of Jiangsu Province from 2000 to 2012. Both the urban expansion and resource consumption showed the fluctuant double growth trend, on the contrary, the growth rate presented a downward trend as same as the regional difference. The decoupiing relationship between urban expansion and resource consumption was unstable, on the whole, it was in a relatively decoupling state. To some extent, the contradiction between urban expansion and resource consumption alleviated since 2006. Each city performed different in the evolution. The influence of urban expansion on resource consumption showing a increasng trend, but it has significant difference among multiple urban types. The rapid urban expansion was the main driving force of the resource consumption, meanwhile, it was also the most important driving factor that led to the growth of influence degree of the urban expansion on the resource consumption. Finally, the pro- posals were put forward to promote the coordinated development of urban expansion and resource consumption, above all, the most important measure was promoting city intensive growth.
