| 摘 要： | 基于武汉市地理国情数据，围绕城市土地资源承载力问题，研究建立了一套城市土地资源承载力评价技术方法。首先，根据土地利用功能进行"三生用地空间"划分，将市、区有关经济统计指标按街道进行了尺度下推；其次，在分析评价适宜建设开发用地、已利用建设用地、可开发用地资源的基础上，开展了土地资源承载状态的综合评价；最后，利用地理加权回归分析方法，分析了人口、经济、交通因素对土地资源承载状态的影响。该方法将城市土地资源承载力评价由传统的人口承载力测算转换为开发建设状态评价，不仅为城市承载力评价提供了一种新的分析思路，也为制定精细化和差异化的城市建设用地资源配置和调控政策提供了科学依据。

| Abstract: | This paper conduct a research on carrying capacity evaluation methods and framework of urban land resources based on data from the geographic condition monitoring of Wuhan City. Firstly, we divide the space type according to the land use and scale down the economical statistic indexes into street scale. Secondly, we establish a comprehensive carrying capacity assessment of urban land resources based on the analysis of the construction suitable land, the constructed land and the construction available land. Finally, geographic weighted regression (GWR) tool is adapted to investigate influence of factors including urban population, economy and traffic. The use of GWR transforms the evaluation of urban land resources carrying capacity from traditional population capacity to the evaluation of development status and capability, which not only provides a new way of analysis for the evaluation of urban carrying capacity, but also offers scientific basis for making accurate and differentiated policy of urban construction land resource allocation. |
