【摘要】：城市土地综合承载力能够反映城市土地承载的资源水平、经济规模、社会发展、环境压力等。从资源、经济、社会、环境等4个方面,构建城市土地综合承载力评价指标体系,采用主成分分析法、聚类分析法对广西全区及其14个市2005—2014年城市土地综合承载力进行评价,分析其时空特征及驱动因素,为提高城市土地综合承载力提供参考。结果表明,2005—2014年广西城市土地综合承载力整体呈上升趋势;2005—2014年广西城市土地综合承载力空间分布差异显著,柳州、桂林、南宁等市属于高承载区,北海、玉林、梧州等市属于较高承载区,其他市承载力随时间变化处于不同等级;经济发达程度是影响城市土地综合承载力的重要因素,但并不能直接代表城市土地综合承载力水平。
[Abstract]:The comprehensive bearing capacity of urban land can reflect the level of resources, economic scale, social development, environmental pressure and so on. From the four aspects of resources, economy, society and environment, the evaluation index system of comprehensive carrying capacity of urban land is constructed, and the principal component analysis method is adopted. Cluster analysis was used to evaluate the comprehensive carrying capacity of urban land in Guangxi and its 14 cities from 2005 to 2014. The spatial and temporal characteristics and driving factors of the comprehensive carrying capacity of urban land were analyzed, which provided a reference for improving the comprehensive carrying capacity of urban land. The results show that the comprehensive bearing capacity of urban land in Guangxi is on the rise from 2005 to 2014. From 2005 to 2014, the spatial distribution of urban land comprehensive carrying capacity in Guangxi is significant. Liuzhou, Guilin, Nanning and other cities belong to high bearing area, Beihai, Yulin, Wuzhou and other cities belong to higher bearing area, and other cities are in different grades with time. The degree of economic development is an important factor affecting the comprehensive bearing capacity of urban land, but it can not directly represent the level of comprehensive bearing capacity of urban land.
