Abstract:

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 differentiation,and the population gravity centers were relatively stable.The main direction of population distribution was from northwest to southeast
