摘要:
构建合理的城镇体系对于区域发展具有重要的作用,而科学划分系统内部的城镇层级是城镇体系规划与研究的基础性工作。在分析安徽省城市现状的基础上,首先从8个方面选择26项指标,建立科学的评价指标体系,然后利用主成分分析计算安徽省16个地级市的城市发展综合得分,最后根据综合得分进行聚类分析。根据分析结果,将合肥、芜湖、马鞍山、蚌埠和铜陵划分为实力型城市;安庆、滁州、淮南、黄山、淮北及阜阳划分为中等型城市;宿州、六安、池州、亳州和宣城划分为潜力型城市。

Abstract:
Building a reasonable urban system plays an important role in regional development, and scientific division of urban hierarchy is the basic work of urban system planning and research. On the basis of analyzing the current situation of cities of Anhui Province, we established a scientific evaluation index system from eight aspects including 26 indicators, and then the principal component analysis was used to calculate urban development points of the 16 cities in Anhui Province. Finally, combing with the cluster analysis method, we divided these cities into three levels. The result showed that, Hefei, Wuhu, Ma’anshan, Bengbu and Tongling are divided into dynamic cities; Anqing, Chuzhou, Cuainan, Huangshan, Huaibei and Fuyang are classified as medium-sized cities; Suzhou, Lu’an, Chizhou, Bozhou and Xuancheng are potential cities.
Key words:  urban hierarchy  principal component analysis  cluster analysis  Anhui Province
