摘要: 以重庆市2001年统计数据为基础,对重庆市2001年生态足迹计算结果表明,该地区人均生态足迹为1.653566 hm2, 人均生态承载力为0.280393 hm2,人均生态赤字为1.373173 hm2,与全国平均水平相比,人均生态足迹高0.5335 hm2 (增加47.64%),人均生态承载力低0.5196 hm2(下降64.95%),生态赤字是全国平均赤字的3.43倍,表明该地区生态足迹超过了当地生态承载能力,区域经济社会发展处于一种不可持续的发展状态.另外,还分析论述了多种渠道解决生态系统超负荷人口、增加科技财政投入、控制环境污染等减少该地区生态足迹的对策.

Abstract: Based on the statistical data of Chongqing,the ecological footprint of Chongqing was calculated in this paper.The results showed that the per capita ecological footprint was 1.653566 hm2,per capita ecological capacity was 0.280393 hm2,and ecological surplus of deficit was 1.373173 hm2.The per capita ecological footprint was 0.5335 hm2(47.64%) higher but the per capita ecological capacity was 0.5196 hm2 (64.95%) lower,and the ecological surplus of deficit was about 3.43 times of the average national level.These results showed that the ecological footprint of Chongqing was beyond the available ecological capacity,and its social and economic development was not sustainable.The strategies on reducing ecological deficit in this region,such as reducing ecosystem population,increasing public finance income,and controlling environmental pollution,were also put forward.
