摘要:

生态足迹是近来测度生态可持续发展的一种定量方法,也是一种用来度量人类活动对生态系统压力和影响的一条新途径。该文对湖北省2002～2006年的生态足迹进行动态分析。结果表明:近5年来,湖北省人均生态足迹由1.89786hm2/人增长到2.4075hm2/人,增加了26.85%;可利用人均生态承载力变化不大,保持在0.54hm2/人左右,以耕地所占比重最大,达67.6%;研究阶段全部表现为生态赤字,生态强度指数增长快速,其指数均大于1,说明湖北省处于生态高负荷运转状态。

Abstract:

Recently,ecology footprint is a method of fixed quantity for testing ecological sustainable development.It is also a new pass for measuring the pressure and influence exerted by mankind activities to ecological system.This paper conducts dynamic analysis on ecological footprint from 2002 to 2006 in Hubei Province.The results indicate that during the past 5 years,the per capita ecological footprint of Hubei Province increased from 1.89786hm2/per person to 2.4075hm2/per person,increased 26.85%.There are not many changes in per capita ecological bearing ability,which remains about 0.54hm2/per person.The proportion taken by arable land is the largest and accounts for 67.6%.The whole research period represents ecological deficit.The index of ecological strength increased rapidly,which is greater than 1.This indicates that Hubei Province is under the estate of heavy load operation.
