中文摘要：

在获取1996～2010年贵州产业结构数据的基础上,以GIS技术为支撑,对贵州县域行政区划图、交通图和DMSP_OLS城市夜间灯光数据进行空间叠加后,结合信息熵和聚类方法,分析贵州县域经济演变的时空格局。结果表明:贵州县域产业结构演化遵循点-轴扩散规律,表现出以省会贵阳为中心,地级市为次中心,沿交通干道逐次辐射的地域重构特征。最后讨论了当前贵州经济发展中存在的问题及其解决办法,以期对贵州的可持续发展起到一定的作用。

英文摘要：

Based on industrial structure data of Guizhou Province from 1996 to 2010 and GIS technology,the evolutive spatial-temporal pattern of county-level economy in Guizhou region was analyzed by information entropy and clustering method after space overlapping of county-level administrative map,county-level circulation map and DMSP_OLS urban night light data.The results indicated that the evolution of industrial structure at county-level of Guizhou region followed the rule of pole-axis diffusion,namely expressed the regional reconstruction characteristics that taking Guiyang City,the capital of Guizhou Province,as center,taking prefecture-level city as sub-center,and gradually diffusing along with the traffic artery.In the end,it discussed the problems existed in economic development in Guizhou province at present and its countermeasures.
