摘　　要：利用传统统计和ESDA方法,在Arcgis和GeoDA等软件的支持下,利用全国第四次、第五次和第六次人口普查分县市统计数据,以城镇化率为测度指标,县级尺度为研究单元,对1990—2010年湖北省城镇化格局及其演变进行分析.结果表明:(1)湖北省城镇化格局的现状特征为:城镇化发展空间不均衡,城镇化中低发展水平地区占主体;主要城镇沿江沿路分布特征明显;一城独大的金字塔型城镇体系仍然较为突出.(2)近20年来,湖北省城镇化发展逐步呈现空间聚集格局,不同区域城镇化水平差异在缩小;武汉城市圈作为区域城镇化"热点区"扩散作用不断增强、辐射范围逐渐扩大;但鄂西南、鄂东北作为区域城镇化的"冷点区"基本没有改变;城镇规模体系日趋合理,特大、大城市聚集效应显著.With the help of Arcgis 9. 3 and openGeoDA and the methods of statistic analysis and ESDA, the study was done by the data of the fourth, fifth and the sixth population census and measured by the urbanization rate indications of country level, the conclusions of urbanization pattern and evolution in Hubei province had been found： firstly, the characteristics of urbanization pattern, the urbanization level in HubeiProvince was unbalanced and the area of low urbanization level accounted for larger proportion; the cities mainly distributed along with the Yangze River and expressway; the urban primacy index was high and the pyramid urban system was obvious. Secondly, in recent 20 years, the spatial pattern of urbanization level in Hubei Province had being gathered gradually and the differences had being narrowed~ the diffusion of Wuhan urban cluster was enhancing and the hotspot of urbanization was gradually expanding, but the southwest and northeast of Hubei Province had always been the non-hotspots on regional urbanization level; the urban system in Hubei Province was getting reasonable sustainably and the proportion of urban population in metropolitan and big cities always occupied the largest.
