摘　　要：研究了栗山天牛Massicus raddei(Blessing)发生与林分因子的相关性。结果表明,栗山天牛在阳坡、坡顶发生较重,随林龄和胸径的增加而加重,与树种组成关系不大。The result showed that the occurrence of M. raddei became more severe with the development of the stand-age and the chest height diameter of Quercus rnongolica. It was more severe on the sunny slopes and slope top. The composition of tree species had little influence on its occurrence.
