摘要
本文运用生态足迹理论模型对贵州省2000年到2015年的林业生态足迹和生态承载力进行了研究。结果表明:(1)2000~2015年贵州省林业生态足迹表现为整体增加的趋势,生态足迹主要由木材、水果和茶叶构成,其他林产品所占比例较小。(2)贵州省林业生态承载力逐年增长,与林地面积的不断增加密切相关。贵州省林业生态供需一直处于盈余状态且逐年增加,同时林业生态效率一直处于增长趋势,表明贵州省林业生态可持续发展程度和森林资源利用率较高。
In this paper,the forestry ecological footprint and ecological carrying capacity of Guizhou Province from 2000 to 2015 were studied by using the ecological footprint theory model.The results showed that :(1) The ecological footprint of Guizhou Province increased from 2000 to 2015,and the ecological footprint were mainly composed of wood,fruit and tea,and the proportion of other forest products was small;(2) The ecological carrying capacity of forestry in Guizhou Province was increasing year by year,which was closely related to the increase of forest land area.Guizhou forestry ecological supply and demand has been in a state of surplus and increased year by year,while forestry ecological efficiency was in the growth trend.This study showed that the sustainable development of forestry ecology and the utilization rate of forest resources in Guizhou Province were higher.
