洞庭湖生态经济区经济差异时空格局

Temporal-Spatial Patterns of Economic Differences in Dongting Lake Ecological Economic Zone

采用传统统计学和空间自相关分析方法对2001—2011年洞庭湖生态经济区县域经济差异时空特征进行了分析.结果表明经济区绝对差异呈持续扩大,相对差异呈波动式缩小;四地市间差异和岳阳、常德内部差异是经济区差异的主要贡献者.高水平县域为地市市区及周围县域,经济发展水平向东高西低、南高北低转变;县域经济空间相关性不显著,呈"四核"空间结构.

Using the methods of traditional statistics and ESDA, the temporal and spatial characteristics of county economy differences in Dongting Lake Ecological Economic Zone were analyzed from 2001 to 2011. The resuits show that the absolute difference of economic zone enlarges constantly, but the relative difference has a narrowing trend; the differences among four cities, internal difference in Yueyang City and Changde City are the main contributions to the differences. High-level counties are urban districts of the prefecture-level city, the level of county economy development has a transition with strong east and weak west, strong south and weak north; The spatial correlation of county economy is not significant, but exhibit a ＂four cores＂ spatial structure.
