基于生态足迹的宝鸡市土地生态承载力评价

Evaluation of Ecological Carrying Capacity Based on Ecological Footprint Model in Baoji City

运用生态足迹法对宝鸡市生态足迹进行计算,结果表明,10年来宝鸡市的生态足迹超过了生态承载力,城市生态系统所受压力偏大;较大的生态赤字反映出目前宝鸡市对生物生产性土地面积的需求已经严重超过区域生态系统的承载能力,区域生态系统处于过度开发利用压力之下。宝鸡市的人均生态足迹超出全球和中国平均水平,宝鸡市生态发展处于不可持续状态。在此基础上提出了缓解宝鸡市生态压力的建议。

The ecological footprint of Baoji city from 1996 to 2005 was calculated by using ecological footprint method.The results showed that during 1996～2005 the ecological footprint of Baoji city exceeded the ecological carrying capacity,the natural ecological system of this city bore great pressure.The high ecological deficit showed that the human load had already gone beyond the regional bio-capacity and the regional natural ecosystem was under great pressure of human activities.The ecological footprint of Baoji city was higher than that of the global and average level of China,so the development of the ecological economy in Baoji was unsustainable.Finally a series of measures to reduce the ecological deficit of Baoji city were brought forward based on the above analysis results.
