摘要
利用传统统计分析方法和ESDA方法相结合,在ArcGIS和GeoDA等软件的支持下,以非农人口城市化为测度指标,从时间、空间、关联性三个侧面对1990—2008年江苏省城市化空间格局进行了分析。结果表明:江苏省城市水平呈现苏南、苏中、苏北逐次下降的空间格局;城市化速度总体上苏中快于苏南,苏南快于苏北;区域城市化水平总体上朝均衡方向发展,处于中等城市化水平的区域逐渐增多;根据城市化水平的空间关联性,江苏省可分为扩散型、极化型、塌陷型和传染型四种不同类型的城市化发展区域。
Thanks to the help of ArcGIS 9.2 and GeoDA 9.5, with the methods of statistic analysis and ESDA, the study is done by the data of non-agricultural population. The urbanization spatial pattern is analyzed from three sides of time series, spatial series and spatial autocorrelation. The following conclusions are found： the level of urbanization in Jiangsu Province successive decrease from south to north. The rate of urbanization in the middle-Jiangsu is faster than it in the south-Jiangsu, and north-Jiangsu is the lowest. The level of urbanization is towards to a balanced direction. The region number of middle-level is gradually increased. According to the relationship between the country and adjacent country, the countries in Jiangsu province can be divided into the diffuse pattern, polarization pattern, sinking pattern and infection pattern.
