基于生态足迹模型的南方红壤丘陵山区可持续发展评价

Evaluation of the sustainable development of red soil hilly regions in southern China based on ecological footprint model

生态足迹模型是研究一个国家或地区可持续发展程度的一种方法,定量反映人类活动对生态环境的影响和破坏程度.通过比较区域人类社会所有消费活动所需的土地(生态足迹)与该区可提供的生物生产性土地(生态承载力)可得出该区的可持续发展状况.文章在生态足迹概念和计算方法的基础上,以福建省南平市2006年统计年鉴数据为依据,计算分析得到南平市2005年的人均生态足迹为1.43320 hm2/人,人均生态承载力为1.40762 hm2/人,生态足迹呈现赤字,为0.02588 hm2/人.数据表明该市人类的生产和生活强度超过了生态系统的承载能力,区域生态系统处于人类的过度开垦状态之下.文章针对改善南平市的生态承载力提出一些改善措施.

The ecological footprint model is a measure of the degree of sustainable development indicators, which can quantitatively measure the human impact on nature environment. The method is used to calculate the ecological footprint from the facet of need and the ecological carrying capacity from the facet of support. Based on its results, the sustainable development situation of a country or an area can be evaluated. Based on the introduction to the con- cept and the calculation method of ecological footprint model, the authors calculated and analyzed the ecological footprints of Nanping City in 2005 according to the data of the statistical yearbooks of Nanping. According to the calculation, the ecological footprint and the ecological carrying capacity and the ecological deficit per capita of Nanping in 2005 were 1. 43320hm^2, 1. 40762 hm^2, 0. 02588 hm^2, The data shows that the human load has already stayed beyond the regional ecological capacity and the regional natural ecosystem is under great pressure of human activities. Furthermore this paper gave some strategies on the enhancement of ecological capacity of Nanping.
