摘要
依据2000年统计数据,以县域为统计单元,建立中国城市数据库。在此基础上,选用非农产业GDP比重、非农从业人员比重、人均GDP、人口密度4个参数构建都市区的门槛指数等模型,同时建立了数字地图。通过分析我国2000年城市体系的空间分布特点,划分出3级,共2个都市连绵区、2个亚都市连绵区和5个城市密集地带,为我国城市建设和区域经济的发展提供了新的依据。
Based on the statistical data of 2000,a database is established,regarding county as a basic statistical unit. By designating four parameters which are,the ratio of nonagricultural GDP to aggregated GDP (excluding agricultural GDP),the ratio of nonagricultural labor force to total,per capita GDP and population density,this paper creates the threshold-indices model and builds up thematic maps. On the basis of the analyses on spatial distribution characteristics of urban system in 2000,Chinese urban areas are divided into 3 grades,including two metropolitan interlocking regions,three sub-metropolitan interlocking regions and five city-intensive regions,which lays new foundation for the construction of urban area and the development of regional economy.
