    摘要:

    土地承载力是资源承载力研究的重要方面, 是评价一个地区可持续发展能力的重要参考依据。以社会经济发展迅速而人地矛盾突出的江苏省为研究区域, 从水土资源支撑系统、经济技术支撑系统、社会支撑系统和生态环境支撑系统4个方面建立了江苏省土地综合承载能力评价指标体系, 采用多因素加权综合评价法对各县(市)进行土地综合承载能力综合评价。根据评价结果将全省分成高承载能力区、中承载能力区和低承载能力区, 整体表现出从东南部-中西部-北部和沿海承载能力逐渐降低的空间分异特征。

    Abstract:

    As an important area of resource carrying capacity researches, land carrying capacity is an important reference basis to evaluate sustainable development ability of a special region. Selecting Jiangsu Province as a study case where has fast socio-economic development speed and prominent man-land contradiction, the paper established the evaluation indicator system of comprehensive land carrying capacity from the four supporting systems including water and land resources, economy and technology, society, and eco-environment. Then, comprehensive land carrying capacity is evaluated by applying the weighted multi-factors synt hetic appraisement method at county level. According to the evaluated results, land carrying capacity of Jiangsu Province is divided into three types , i.e., high, moderate, and low carrying capacities. On the whole, it decreased from south east, midwest to north and seaboard of Jiangsu Province.
