摘要
运用生态足迹分析方法,以相关统计资料为依据,对成都市2000～2004年的生态足迹进行了计算和研究,比较并分析了成都市生态足迹的变化规律及其原因。结果表明:①成都市生态足迹需求逐年增加,生态承载力不断减少,生态赤字从2000年的1.1904hm2上升到2004年的1.3601hm2。说明人类活动对区域生态系统的影响已超出了生态承载力的阈值,区域生态系统的结构和功能亟需调整;②各类土地生态足迹中,化石能源地生态足迹最大,其次为草地和耕地。反映出成都市经济的发展很大程度上依赖自然资源的消耗;③从各类土地生态足迹发展趋势看,除耕地逐年减少外,其余均不断增大;④万元GDP生态足迹呈下降趋势,表明成都市的资源利用效率明显提高。分析了生态赤字的直接原因,提出了成都市在进行可持续发展过程中应采取的对策措施。
This paper introduces the concept of ecological footprints（EF） and a calculation method,calculates the ecological footprints from 2000 to 2004 in Chengdu City,and analyzes the laws and causes of the changes vertically in its ecological footprints. The results show： （1）the ecological deficits of Chengdu were 1.1904hm^2, 1.2049 hm^2,1.2628 hm^2,1.3212 hm^2 and 1.3601hm^2 per capita from 2000 to 2004,which means the structure and functions of the regional eco-economic system should be adjusted; （2）the EF of the fossil energy land was the largestest,showing that the highly intense development pressure to ecosystem; （3）the EF of the cropland has and heavy consumption of energy had brought great decreased gradually,while the others have grown every year. （4）the comparison of EF demand of ten thousand yuan GDP puts forward that the efficiency of biological resources usage of Chengdu City is becoming higher.Based on the analysis of the factors influencing the ecological footprints of Chengdu,some measures for solving the problems are put forward.
