摘要
古树是自然界赋予人类宝贵的不可再生资源,具有重要的保护价值。本文以乌东德水电站淹没区内117株古树作为研究对象,运用AHP模型,选取等级指标、形态指标、生长指标、自然干扰、人为干扰、生长环境等6个指标构建古树保护重要性评价指标体系,计算出乌东德水电站水库淹没区117株古树保护重要值,其中26株古树保护重要值大于50,移栽到业主营地专人看护;88株古树保护重要值小于50,移栽到移民安置点就近保护。
Ancient trees are human precious and non-renewable resources,which have important value.As an example of 117 ancient trees in wudongde hydropower station,an evaluation index system of protection importance of ancient trees was put forword,which selected 6 indexes as grade index,morphology index,growth index,natural disturbance,human disturbance and growth environment by AHP model.The results showed that 26 trees of protection importance value over50 will be transplanted to the owner camp,while 88 trees of protection importance value below50 will be transplanted to vicinal resettlement arrangement spots.
