中文摘要：

基于1990～2010年人口统计数据,结合数理统计分析方法和GIS空间分析方法,探讨了武汉城市圈人口空间分布的时空格局分异规律,得出以下结论：（1）圈域人口规模持续稳步增长,可划分为1990～1999年剧增阶段、1999～2006年滞涨阶段和2006～2010年稳步增长3个阶段;（2）圈域人口格局表现为东西向的交通廊道（宜黄-黄黄-黄小高速）指向且不断得到强化;（3）人口密度的空间变异系数先升后降,圈域人口分布的空间差异先扩大后缩小,但空间差异的绝对水平即空间异质性特征仍较为突出;（4）人口分布的动态变化格局表现为＂圈层式＂空间分异,圈域人口分布的主要方向为西北-东南向,且在进一步的往东南方向集聚;（5）圈域人口格局是自然地理条件、区域公共政策、社会经济发展和交通运输条件共同作用的结果。

英文摘要：

According to the population statistics data from 1990 to 2010 ,and based on the mathematical statistics analysis method and GIS spatial analysis method, this article analyzed the spatio-temporal pattern characters of population distribution in Wuhan Metropolitan Area. The result revealed that the population had a continued and steady growth. It could be divided as three periods,rapid growth period（from 1990 to 1999） ,stagflation growth period（from 1999 to 2006）,and steady growth period（from 2006 to 2010）. The population had distributed over the main highway sucn as Yichang-Huangshi Highway and Huangshi- Huangmei Highway,and the tendency was constantly strengthened. The coefficient of variation of the population density was firstly increased and then decreased. The population distribution in Wuhan Metropolitan Area was firstly dispersed and then agglomerated, and the spatial heterogeneity which means the level of spatial difference was still obvious. The dynamic change of population distribution was circle spatial dif- ferentiation, and the population gravity centers were relatively stable. The main direction of population distribution was from northwest to southeast.
