生态足迹模型通过将人类的全部消费所占用的生态足迹与自己所拥有的生态容量相比较来反映人类活动对生态系统的压力,是近年来较为流行的评价区域可持续发展能力的定量方法。本文运用生态足迹模型,对恭城实验区2001——2012年的生态足迹进行计算和动态分析,并引入万元GDP生态足迹、生态足迹多样性指数以及生态经济系统发展能力指标对其可持续发展能力进行评价分析。结果显示,恭城实验区2001——2012年间呈生态赤字状态,且人均生态赤字逐年增加,生态供需矛盾不断加剧。万元GDP生态足迹呈下降趋势,生态足迹多样性指数呈微幅上升趋势,而生态经济系统发展能力则有明显的提高,表明恭城实验区可持续发展能力正处于以资源消耗为基础的较低水平向高水平发展的过渡阶段。
The ecological footprint model reflects the human activities’ pressure on the ecosystem by comparing the ecological footprint occupied by all human consumption with the ecological capacity owned by them. It is a quantitative method that is more popular in recent years to evaluate the sustainable development ability in the region. This paper uses the ecological footprint model to calculate and analyze the ecological footprint of Gongcheng experimental area from 2001 to 2012 and introduces the ecological footprint of 10,000 yuan GDP, the diversity index of ecological footprint and the index of the development capability of ecological and economic system for its sustainable development Ability to carry out evaluation and analysis. The results showed that Gongcheng Experimental Zone was in an ecological deficit state from 2001 to 2012, and the per capita ecological deficit increased year by year, and the contradiction between ecological supply and demand was aggravated. The ecological footprint of 10,000 yuan GDP is on a downward trend and the diversity index of ecological footprint shows a slight upward trend while that of eco-economic system shows a significant increase. It shows that the sustainable development capability of Gongcheng Experimental Zone is at a level of resource consumption-based Low level to a high level of development of the transitional phase.
