摘要:

以江苏省各地市生态足迹为研究对象,采用基于能值分析的生态足迹方法计算和分析2009年江苏省13个地市的生态足迹。研究结果表明:总体上看,江苏省处于生态赤字状态,各地市都处于强不可持续状态,资源生产效率从南到北呈明显梯度变化。具体表现为:1)人均生态足迹、人均生态承载力和人均生态赤字都表现为苏北地区>苏中地区>苏南地区;2)各市的可持续发展指数都小于0.1,其区域差异为南北两端好于中部,南部的镇江市、苏州市最好,苏中的扬州市、南通市较差;3)苏南地区资源生产效率明显高于苏中和苏北地区,而苏中地区又明显高于苏北地区。

Abstract:

This paper applies energy values to calculate and study the ecological footprints in Jiangsu's 13 cities in 2009 and generally shows an ecological deficit, an intense unsustainability and an S-N gradient. The northern Jiangsu ranks top in the ecological footprint, capacity and deficit per capita, following by central and then southern. The sustainable developing indexes in all cities are less than 0.1 with a regional variance that south and north ends are higher than the central, the southern Zhenjiang and Suzhou seat the foremost, and Yangzhou and Nantong in the central behind. The resource production efficiency in southern is higher than in the central, and following by in the northern.

Key words: energy value analysis, ecological footprint, variance, Jiangsu province
