森林冰雪灾害致损因子研究综述

Review on Factors Affecting Snow and Ice Damage of Forest

对国内外森林冰雪灾害的研究进行综述和分析,将森林冰雪灾害的致损因子总结为地形因子、林分因子和气象因子,涉及的具体指标分别为坡度、坡向、坡位、海拔、树种组成、林分龄组、林分密度、温度、风速、累计霜冻/降雪日数、积雪持续日数、积雪深度。分析认为,筛选可适用于较大尺度森林冰雪灾害研究的通用致损因子,并在此基础上开展森林冰雪灾害评估体系研究将是未来森林冰雪灾害研究的重要方向。

Reviews were made on researches of forest snow and ice disaster at home and abroad,and as well as on damage factors such as terrain,forest types and meteorology.Their indicators involved gradient,aspect,slope position,elevation,tree species composition,stand age,stand density,temperature,wind speed,cumulative frost and snow days,snow cover days and depth.Analysis showed that further researches shoud be focused at common damage indicators for forest snow and ice disaster in large area,and their assessment system.
