【摘要】：紧凑型城市发展是相对于分散型城市发展较为经济的一种发展模式。为探索东北三省城市紧凑度现状及特征,首先,从土地利用紧凑性、经济紧凑性、人口紧凑性、基础设施紧凑性,环境协调等方面切入,建立紧凑度评价的指标体系,运用熵值法对东北三省地级及以上城市的紧凑度进行了评价,并从空间和数量统计角度,应用SPSS软件,归类分析了城市紧凑度的分布特征;其次,以计算得到的紧凑度指数为基础,借助GIS软件,运用空间全局/局部自相关分析方法对东北三省城市紧凑度分布的相关性进行了分析,并利用地理加权分析方法,对紧凑度与影响紧凑度分布的主要因子的关联性进行分析。研究结果表明,东北三省城市紧凑度呈现出较为突出的极化分布现象,不同主因子对紧凑度分布影响的差异性显著。
[Abstract]:Compact city development is a more economic development mode compared with decentralized city development. In order to explore the present situation and characteristics of urban compactness in the three provinces of Northeast China, firstly, from land use compactness and economic compactness. From the aspects of population compactness, infrastructure compactness and environmental coordination, the paper establishes the index system of compactness evaluation, and evaluates the compactness of three cities in Northeast China by entropy method. From the perspective of spatial and quantitative statistics, the distribution characteristics of urban compactness are classified and analyzed by using SPSS software. Secondly, based on the calculated compactness index and with the help of GIS software, this paper analyzes the correlation of the compactness distribution in the three cities of Northeast China by using the spatial global / local autocorrelation analysis method. The relationship between the compactness and the main factors affecting the compactness distribution is analyzed by the method of geographical weighted analysis. The results show that the compactness of the three provinces in Northeast China shows a prominent polarization distribution phenomenon. The effect of different main factors on the compactness distribution is significant.
