摘要
运用生态足迹的理论和计算方法和生态足迹指标对葫芦岛市生态承栽力进行了研究。研究表明:2000年~2003年人均生态足迹达2.3764hm^2,全市生态足迹达642.2529×10^4hm^2,人均生态承栽力0.5956hm^2,全市生态承载力160.9147×10^4hm^2,人均生态赤字1.7808hm^2,全市生态足迹赤字高达481.3382×10^4hm^2。葫芦岛市生态系统处于人类过度开发利用和压力下,区域经济社会发展处于不可持续状态。生态足迹模型为研究生态环境的承载力提供了一种廉价而快速的计算框架,作为确定葫芦岛市生态承栽力的方法与模式,简单、综合而且实用。
This article introduces the theories of the ecological footprint, calculation methods and the ecological footprint index, and then calculates the ecological capacity of Huludao City. Research results show that: per capita ecological footprint is 2. 3764 hm^2,and ecological footprint of the whole city is 642. 2529 * 10^4hm^2 ,and per capita ecological capacity is 0. 5956 hm^2, and ecological capacity of the whole city is 160. 9147 * 10^4hm^2 ,and per capita ecological deficit is 1. 7808 hm^2 , and ecological deficit of the whole city is 481. 3382 * 104hm^2. The fast development of economy is achieved by excessive consumption of resources and destruction of ecological environment, the development of economic society in this district is not sustainable development. The ecological footprint provided a kind of cheap and fast calcula tion frame for the ecological capacity studies, and it is the simple, comprehensive and practical to calculate the ecological capacity of Huludao City.
