摘　　要：结合江苏省发展实际,在重新审视土地承载力的基础上,从水土资源、生态环境、经济技术、社会发展等方面出发构建土地综合承载力评价体系,采用因子分析法、聚类分析法,对江苏省1994-2008年以及13个城市2008年的土地综合承载力状况进行综合评价。分析其时间特征以及空间差异状况,进而分析了驱动因素和相应的政策内涵,为改善区域土地综合承载力状况、谋求进一步可持续发展提供参考。结果表明:(1)1994-2008年江苏省土地综合承载力水平总体不断提高;(2)2008年江苏省土地综合承载力水平空间差异较大,并呈现一定的地域相近性;(3)经济发展水平是影响土地综合承载力的一个重要因素,但并不能直接代表土地综合承载力水平的高低。Combined the realitic development of China and based on taking a new look at the land＇s comprehensive carrying capacity,this article structured the appraisal system of the land＇s comprehensive carrying capacity from the fields of land and water resource,environment,economical technology and social development,synthetically evaluated the land＇s comprehensive carrying capacity in Jiangsu Province from the year 1994 to 2008 and that of its in 13 cities in 2008 by the fator analysis and the cluster analysis.The paper analyzed the situation of temporospatial variations,and then found the driving force and the relevant policy connotation,thus to provide the reference of improving the regional land＇s comprehensive carrying capacity and striving for sustainable development.The results showed that（1） The level of land＇s comprehensive carrying capacity in Jiangsu province from the year 1994 to 2008 was increasing;（2） The level of land＇s comprehensive carrying capacity in Jiangsu province was comparatively large in 2008,and moreover presented a certain regional similarity;（3）The level of economic was an important fator,but can＇t reflect the high-low of land＇s comprehensive carrying capacity.
