浙江省主要城市空间形态演变及城镇化质量评估

Spatial Form Evolution and the Evaluation of the Quality of Urbanization in Zhejiang Province

"城市化"是当今中国城市发展的重要战略方向,城市形态分析与城镇化质量评估是城市化研究的基础理论问题.文章借助RS和GIS技术提取出浙江省11个主要城市在1993年、2003年和2014年的建成区信息,并利用形状指数、紧凑度、分形分维、扩张速度和扩张强度及城市重心转移等指标对浙江省城市形态进行了测度.并基于熵值法对社会、经济、人口、环境等共23个因子建立评价指标体系,对不同城市的城镇化质量进行评估并提出相关建议.

＂Urbanization＂ is an important strategy for the development of Chinese cities, and urban form analysis and quality evaluation are the basic theoretical issues of studying urbanization. This paper extracts information of 11 main cities of Zhejiang Province in 1993, 2003, 2014 based on RS and GIS technology. By using indexes such as shape, compactness, fractal dimension, strength of the expansion, and urban shift, etc., it measures urban forms of Zhejiang Province. It also establishes an evaluation system concerning the 23 factors of society, economy, demography and environment, etc. based on entropy method. Finally, it assesses the quality of different cities＇ urbanization and makes recommendations.
