摘　　要：对云南省大关县4种竹林经2008年1月特大强降温冰雪天气过程后的受其冰雪灾害损害的情况进行了调查研究。结果表明:(1)慈竹林受损比水竹林、斑竹林和筇竹林严重;(2)随海拔高度的升高4种竹林的受损随之严重;(3)慈竹、斑竹和水竹3种竹林的受损率与其竹林立竹密度的大小呈正相关,而筇竹林的受损率则随其竹林立竹密度的增加而下降;(4)同一竹林胸径大的竹子比胸径小的竹子更容易受损害而折断和破裂。The damage of heavy snow in January 2008 on four kinds of bamboo forests in Daguan County of Yunnan province was investigated. The results showed that ： 1 ） Neosinocalamus affinis was damaged more seriously than Phyllostachys heteroclada, Ph. bambusoides and Qiongzhuea tunidinoda ; 2） With the increase of altitude, the damage of bamboo became more serious; 3 ） As far as three species such as Neosinocalamus affinis, Phyllostachys Ph. bambusoides were concerned, the damage rate was positively correlated with planting density, whereas the damage of Qiongzhuea tumidinoda decreased with the increasing of planting density; 4） Within a bamboo forest, the bamboo individual with bigger DBH was more susceptible to snow damage.
