根据新型城镇化的内涵构建了湖南新型城镇化水平的评价指标体系,运用层次分析法确定各指标的权重,利用统计数据分别测算了2002年、2007年和2012年湖南新型城镇化的综合得分,使用ArcGIS的空间分析功能对湖南新型城镇化水平进行分类.分析得出其空间演变特征为:①湖南新型城镇化水平整体不高,市域间总体差异较大,但呈缩小趋势;②湖南各市新型城镇化水平出现空间变化明显和高值中心扩大,低值中心不变的特征;③湖南新型城镇化水平高值区域有不断向西扩展的趋势,且东部集中趋势强化.
On the basis of the connotation of new urbanization, this paper established the index system of new urbanization level, and by the ana- lytic hierarchy process( AHP), determined the weights of the index to get the comprehensive score of new urbanization level in 2002,2007,2012 of the 14 cities in Hunan Province. By the spatial analysis of ArcGIS, the pattern and space distribution of new urbanization level in the three years of Hunan Province were obtained. And the results showed:(1)Hunan new urbanization level was not high as a whole,the overall difference between city region was large and narrowing. (2)Hunan new urbanization level appeared obvious spatial variation and high center expansion, low center unchanged. (3)Hunan new urbanization level area was constantly westward expansion trend, the east central trend also strengthen.
