基于生态足迹的从江县可持续发展定量分析

为了更深入地了解可持续发展的程度,有关学者努力探寻能定量衡量国家或地区发展的可持续模型和方法,其中生态足迹就是一个通过相同单位比较人类需求与自然供给的易懂、清晰、直观模型。文章基于生态足迹模型对一个少数民族众多的贫困县进行定量分析,结合一些相关指标,进行地区间横向对比。研究结果表明,2004年从江县的人均生态足迹为1.30007hm^2,人均生态承载力为1.53896hm^2,虽有人均生态盈余＋0.05422hm^2,但根据中国可持续发展等级,从江属弱可持续发展等级。依据分析弱可持续发展的原因提出了可持续发展对策。

The Quantitative Analysis of Congjiang County about Sustainable Development Based on Ecological Footprint

In order to assess the level of sustainable development, some scholars studying in this field have made great effort in finding sustainable indicator and setting up model which can quantitatively evaluate country and region development. Afterward, many indicators and models appeared. Ecological footprint model is easily-understood, clear and visual model which compares human need to natural supply through same unit. In present paper, Congjiang, a minor nationality county in Guizhou province, was analyzed quantitatively and compared with other areas using analysis results. The result indicated that the ecological footprint of Congjiang was 1. 300 07 hm^2 per cap in 2004, while the ecological carrying capacity was 1. 538 96 hm^2 per cap. Although ecological remainder had ＋ 0. 054 22 hm^2 per cap, Congjiang was still at weak sustainable development level on the basis of the rank of sustainable development in China. So, some sustainable countermeasures were put forward according to analytic reasons of weak sustainable development.
