承德市1999～2004年生态足迹与土地生态承载力分析

Analysis of Ecological Footprint and Ecological Carrying Capacityin Chengde from 1999 to 2004

根据生态足迹原理和方法，用1999～2004年承德市统计数据计算出7年来承德市生态足迹和生态承载力。结果表明1999～2004年承德市人均生态足迹呈上升趋势。1999～2004年承德市人均生态足迹大于土地生态承载力为生态赤字，必须改变消费和生产方式，树立科学发展观，走集约、节约、高效型的循环经济发展模式。从横向比较看，承德市6年平均人均生态足迹仅为全球1993年平均水平的43．69％，是北京、天津、河北1990～2003年平均水平的48．17％、50．98％、50．98％，是全国1999年水平的91．98％，说明承德市的经济发展水平略低于全国平均发展水平，在京津冀地区属于相对发展滞后区。

Ecological footprint is an important indicator for measuring ecological carrying capacity in the research field of sustainable development. Owing to its convenient, precise and feasible characters, ecological footprint is widely used in the world. Adopting the ecological tbotprint principle and model, taking Chengde as a case, its ecological footprints from 1999 to 2004 was calculated and analyzed according to the data from the statistical yearbook. The dynamic change trends of its consumption and supply of all land types were analyzed respectively. The results showed that the ecological footprints per capita in Chengde appeared increasing tendency. In order to realize the sustainable development of ecological economy, it was urgent to change consumption and production patterns.
