| 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 carrying capacity of urban land can reflect the resource level,economic scale,social development and environmental pressure of urban land carrying.The assessment indicator system of urban land comprehensive carrying capacity was constructed from the 4 aspects of resource,economy,society,environment,and principal component analysis and cluster analysis were used to evaluate the urban land comprehensive carrying capacity of Guangxi and the 14 cities in 2005-2014,and analyzed its spatial and temporal characteristics as well as the driving forces,with the aim to provide references for improving the urban land comprehensive carrying capacity.The results showed that,the overall urban land comprehensive carrying capacity in Guangxi increased in 2005-2014,and there were significant differences in the land comprehensive carrying capacities among the cities in Guangxi in 2005-2014,in which Liuzhou,Guilin,Nanning belonged to the regions with the highest carrying capacity,while Beihai,Yulin,Wutong belonged to the regions with high carrying capacity,and the carrying capacities of the other cities changed with the changes of time.The economic development degree was an important factor influencing urban land comprehensive carrying capacity,but could not directly represent the urban land comprehensive carrying capacity level. |
