摘要
在介绍生态足迹模型计算方法的基础上,将重庆市的生态足迹分为生物资源、能源、环境污染消费3个方面,对重庆市2003年~2005年的生态足迹进行了实证研究.结果表明:重庆市2003年~2005年人均生态足迹从1.526 665 hm2/人增加为1.80 hm2/人, 重庆市可利用的人均承载力较低,总的生态赤字逐年增加,2005年达到为1.342 527 hm2/人,表明重庆市生态占用已远远超过生态承载力,处于不可持续发展状态.针对其状况,提出相应的可行性对策:改善农业生产条件,加快生态环境建设;加强产业结构调整;充分应用GIS (地理信息系统);充分发挥政府的监督、引导作用;实施以"技术"为导向的对策;搞好城市规划,减少生态需求.
On the basis of introducting the ecological footprint model, dividing ecological footprint of Chongqing into living resources, energy, environmental pollution, having carried on the positive research during 2003 - 2005. The results showed: the per capita ecological footprint increased from 1. 526 665 hm2 to 1.80 hm2 in Chongqing during 2003 - 2005, the overall ecological deficit has been increasing annually, the ecological deficit has reached 1. 342 527 hm2 in 2005. It shows the ecologi- cal footprint has far exceeded the ecological carrying capacity and is unsustainable development in Chongqin. To this situation, putting forward the corresponding feasible countermeasure:improve the agricultural working condition, accelerate the construction of ecological environment; strengthen industrial structure adjustment;fully apply GIS (geographical information system) ;take “technology” as direction;fully exert intendance and direction of government;do the urban planning well, reduce the ecological demand.
