基于鄱阳湖生态经济区县域城市建成区和城市人口数据，引入Getis-Ord Gi*指数，构建用地扩张-人口增长协调性系数CI ，对经济区31个县域进行时空协调性综合分析。结果表明：2001—2012年鄱阳湖生态经济区土地城镇化水平及人口城镇化水平表现出同步增长趋势，2者呈显著正相关；县域间土地城镇化进程空间差异较大，表现出南快北慢的总体趋势，人口城镇化进程差异相对较小；城市用地扩张与人口增长G值均呈高值集聚、低值分散的特征，南昌市为高值中心；人口城镇化与土地城镇化整体协调，但县域间协调性系数存在显著的非均衡性和空间差异性，CI值呈“特大城市﹥大城市﹥中等城市﹥小城市”的态势，昌九、浙赣线所组成的“┸”字型地带周围县域CI值较高，滨湖区及边缘区县域则较低。

Based on urban built-up area and population data of Poyang Lake Ecological Economic Region in 2001-2012,the paper introduces Getis-Ord Gi* index and builds coordination index CI of land expansion-population growth,then analyses the coordination state between urban land expansion and population growth with county as study unit. The results suggest that:From year 2001 to 2012,a great increasing and a highly positive correlation ex-isted among land and population urbanization. However,a large difference among the counties’processes of land ur-banization seems to overall trend of“south faster than north”,while the difference between population urbanization is relatively small. Therefore,the G value of urban land expansion and population growth appears to high value ag-glomeration and low dispersion,Nanchang is the high value center. The coordination coefficient of megacities tends to larger than medium-sized cities’which is smaller than big cities’but larger than small cities’,and has apparent regional differentiation that the coordination index of zone composed of Nanchang-Jiujiang railway and Zhegan rail-way is higher than the CI of lakeshore district.
