惠州市可持续发展的生态足迹分析

生态足迹方法是一种定量衡量人类对自然资源的利用程度以及自然界为人类提供生命支持服务功能的新方法。以惠州市2002年基础数据为依据进行计算分析,得出惠州市2002年人均生态足迹为1.335hm2,人均生态承载力为0.610hm2,人均生态赤字为0.725hm2。从出现生态赤字的角度来看,惠州市目前人地关系呈现紧张趋势,结合生态足迹多样性指数、生态承载力发展度以及万元GDP生态足迹等指标对惠州市可持续发展状态进行综合评价表明:与广东省和全国平均水平相比,惠州市在资源利用上效率较高,其发展潜力相对较强。

The Ecological Footprint Analysis of Sustainable development in Huizhou

The ecological footprint is a new method to estimate the level of natural resources utilization and the ecological carrying capacity of the nature. Its theoretical framework and calculation method are introduced in this paper. The ecological footprint ledger is composed of four main sections. The first is basic biotic resources consumption; the second is water resources consumption; the third is energy consumption; and the forth is trade balance. Based on the ecological footprint concept and analysis framework, the ecological footprint of Huizhou city in 2002 was calculated. The results show that the ecological footprint was 1.335hm2/cap; the ecological carrying capacity was 0.610 hm2 /cap; the ecological deficit was 0.725hm2/cap; the ecological footprint diversity was 1.3808; the ecological footprint per 10000 yuan GDP was 0.719 hm2. There were some problems in sustainable development of Huizhou, because ecological footprint was much more than ecological carrying capacity. However, comparing Huizhou City with Guangdong Province and China, it was shown by footprint diversity, ecological carrying development capacity and the ecological footprint per 10000yuan GDP that the utilization mileage of natural capacity in Huizhou is higher and its development potential is stronger.
