安徽省新型城镇化质量空间差异的聚类分析

Evaluation on Spatial Difference of Urbanization Quality in Anhui Province Based on GIS and Cluster Analysis

运用GIS和聚类分析方法客观分析安徽省新型城镇化质量的空间分布差异及其原因,研究结果表明:(1)新型城镇化质量最高的城市有3个,占样本总数的18.8%;较为优越的城市有11个,占样本总数的68.7%;较差的城市有2个,占样本总数的12.5%。(2)安徽省城镇化质量的空间分布呈现环状特征,高城镇化质量的城市集中在合肥都市圈和皖江城市带的大城市,中高、中等城镇化质量的城市分布在高城镇化质量城市的外围。(3)高城镇化质量的城市主要是大区域级别的城市,在经济、社会、文化方面发展势头良好,但生态环境综合指数低,成为新型城镇化建设的制约因素;中高和中等城镇化质量的城市经济、社会、文化、生态指数均处于中等水平,在城镇化建设中要注重传统产业的升级改造;低城镇化质量的城市其制约因素表现为经济指数偏低,产业结构单一,三次产业发展不均衡,在城镇化建设中要注重新兴产业培育。

The article objectively analyses new urbanization quality of space differences in Anhui province using cluster analysis method. The results show： （1） the cities of the most superior urbanization quality have 3 samples, accounting for 18. 8% of the total samples; more superior cities have 5 samples, accounting for 31.2% of the total samples, poor cities have eight, accounting for 50% of the total samples. （2） the distribution of urbanization quality in Anhui province shows ring space characteristics, and the cities of high quality urbanization are concentrated in the Hefei metropolitan area and the periphery city belt along Changjiang. （3） The cities of high quality are main regional level cities. They have a good development in the economic, social and cultural aspects, but the comprehensive index of ecological environment is low, becomes a constraining factor in the construction of the new urbanization; The cities of moderate urbanization quality have middle level index in economy, society, culture and ecological. They should focus on the transformation and upgrading of traditional industries in the process of urbanization; the restricting factor so flow urbanization quality is that economic index is low, single industrial structure, and three industrial development iS not balanced. They should pay attention to the cultivation of new industries in the process of urbanization.
