摘要
生态足迹是分析国家或地区自然资源可持续利用的重要指标。本文依据重庆统计年鉴等自然资源生产与消费数据、人口数据,采用可变世界单产法计算了1997～2006年重庆市生态足迹。结果表明在研究时段内重庆市人均生态足迹由2.3540059hm2升至2.9084383hm2,增长率为23.55%。与同期不断减少的生物供给力相比较,计算出重庆生态赤字在逐年加剧,人均赤字由1.83733hm2上升至2.44216hm2,增长了32.92%,并分析了重庆各类土地生态足迹、生物供给力和生态盈亏变化的原因,针对生态足迹及生态赤字的影响因素,提出解决重庆生态赤字加剧问题的对策。
Ecological footprint is an important indicator to analyze the sustainable use of natural resources .In this study ,We got the data of resources production and consumption, population, and land use from CHONGQING STATISTICAL YEARBOOK .We calculated the ecological footprint of Chongqing during the period from 1997 to 2006 with the method of variable world average yield. The results are as follows： the ecological footprint has grown from 2.3540059hm^2/cap to 2.9084383hm^2/cap with the increase rate of 23.55 %. We find that the ecological deficit has been more and more serious, which is from 1.83733 hm^2/cap in 1997 to 2.44216 hm^2/cap in 2006 with the increasing rate of 32.92% ,through comparing the ecological footprint with the decreasing biological capacity of the same period. And we have analyzed ecological footprint, ecological capacity and ecological deficit of Chongqing, the influencing factor specifically for ecological footprint and ecological capacity, the countermeasure bringing forward the problem resolving Chongqing ecological footprint deficit aggravating.
