摘要
运用生态足迹模型的时间序列分析方法,对位于三峡库区腹心的重庆市万州区1990-2008年的生态足迹、生态承载力和生态赤字进行了分析。研究结果表明:万州区人均生态足迹从1990年的0.698 hm2/人上升到2008年的1.584 hm2/人,年均增长率达4.65%,呈日趋增大的趋势;但是生态承载力却逐步减小,整个万州区均出现生态赤字。万州区生态足迹贡献较大的是人均耕地、草地、水域、建筑用地和化石燃料用地,所占比例分别为30.63%,25.56%2,.80%8,.99%和30.44%。针对万州区经济社会的可持续发展态势提出了相应的对策与措施建议。
The ecological footprint, ecological carrying capacity and ecological deficit from 1990-2008 of Wanzhou District of Chongqing Municipality are analyzed by the time series analysis of Ecological Footprint Model. The per capita ecological footprint of Wanzhou district, which is located in the center of the Three Gorges Reservoir region, increased from 0. 698 hm2 per person in 1990 to 1. 584 hm2 per person in 2008, up 4.65% annually; whereas the ecological carrying capacity dropped gradually, consequently with ecological deficit spreading all over the district. Cultivated land, grassland, water area, land for construction and land for fossil fuels made significant contributions to the ecological footprint of this district, respectively accounting for 30.63%, 25.56%, 2.80%, 8.99% and 30.44%. Measures and suggestions are also proposed for the sustainable economic and social development of the district.
