由于人口增长和城市化，中国的区域生态环境面临着严峻的挑战。因此，基于生态足迹理论对生态足迹和生态承载能力的动态演化进行研究势在必行。为此，本文以江苏省南京市、南通市、淮安市为研究对象，通过对江苏省典型城市生态状况的动态演变特征的探讨，对江苏省中国的生态状况及其内部差异进行了评价。结果表明，江苏省人均生态承载力有所提高，但由于公共土地利用规划不力，耕地生态赤字普遍较大。为了保护耕地，提高其利用率，建议高效利用资源，提高生态承载能力，加强生态修复，减少生态赤字，在农村地区提供平等的设施，减少城镇化。
The regional ecological environment has been facing serious challenges in China due population growth and urbanization. Therefore, it is imperative to study dynamic evolution of ecological footprint and ecological carrying capacity based on the ecological footprint theory. For this purpose three cities namely, Nanjing, Nantong, and Huai'an of Jiangsu province of China were analyzed to estimate the ecological status of the province and its internal differences by discussing the dynamic evolution characteristics of the provincial and typical urban ecological conditions. The results indicated that per capita ecological carrying capacity of Jiangsu province has increased; however, the ecological deficit of cultivated land was generally large due to poor public land use planning. In order to protect cultivated land, and improve its utilization it is recommend to efficient use of resources to improve the ecological carrying capacity, strengthen ecological restoration to reduce ecological deficits, and provision of equal facilities in village areas to reduce urbanization.
