南渡江流域生态经济系统可持续发展评价——基于生态足迹分析法

Sustainable development assessment of ecological economic system for Nandu River Basin : Based on ecological footprint analysis method

为了探讨南渡江流域生态经济系统的可持续发展能力,利用生足迹模型对南渡江流域2009年的生态足迹进行了计算和分析,并与世界其他国家和地区作了比较分析。结果表明,2009年南渡江流域不存在生态赤字,且流域人均生态足迹供给高于其需求量,是全国人均生态足迹供给量的2倍,人均生态盈余为0.335 395 hm2/cap。通过人均生态协调系数的计算,ds=1.397 6<1.414 0,表明本地区的生态足迹供给与需求是基本协调的,生态经济系统发展表现为基本可持续状态。

In order to investigate the ecosystem sustainable development ability in Nandu River Basin,the ecological footprint of Nandu River Basin in 2009 was calculated and analyzed by using footprint model,and the comparative analysis of the watershed with other countries and regions in the world was carried out.The results show that the Nandu River Basin did not exist the ecological deficit and the basin ecological footprint supply of per capita was higher than its demand which was 2 times of the national average ecological footprint supply,and the per capita ecological surplus wais 0.335 395 hm2/cap.Thought the per capita ecological coordination coefficient calculation,ds = 1.3976〈1.414,indicating that the ecological footprint supply of this region was coordinate with its demand and the ecological economic system development was basic sustainable performance.
