中国省会城市紧凑程度综合评价

Comprehensive Analysis of Urban Compactness of Provincial Capital Cities in China

研究目的:基于"紧凑城市"的理念,利用城市建设用地、城市居住用地及工业—商业—交通用地、人口密度和城市密度4组变量揭示近10年来中国城市土地利用和人口增长态势,并以城市密度的形式对省会城市之间的土地利用和人口发展进行比较分析。研究方法:文献资料法、实证分析法。研究结果:中国省会城市建设用地、居住用地、工业—商业—交通用地扩张速度惊人,中国省会城市基本上处于工业导向型城市发展阶段。省会城市建设用地人口密度、城市居住人口密度呈下降趋势,城市用地增长速度快于城市人口增长速度。研究结论:结合城市建设用地和城市人口密度,可以将中国省会城市按照特性分为三类,但城市紧凑程度的多样性可能与很多因素相关,未来的研究需要引入更多的变量。

The purpose of the study is to analyze the relationship between urban land use and population growth of provincial capital cities in China on the basis of Compact City concept. Four sets of variables such as construction land situation, residential land together with industrial commercial and traffic land, population density, urban density were used. Methods of documentation and case study were employed. This study revealed general urban land use statuses and population increase trends in the last ten years in China. The results indicate that the expanding speed of urban areas in these cities was very fast. In most cities, the growing speed of residential industrial commercial and transport areas was faster than that of construction area. The provincial capital cites are basically in a period of industry-oriented urban development. With the development of urbanization, the population density of construction area and residential area keeps decreasing. The increasing speed of urban land use is faster than that of urban population. Basing on this conclusion, we classify Chinese provincial capital cities into three types. The diversity of urban compactness can result from interaction of many factors, and more variables might be introduced for better evaluation.
