摘　　要：[目的]了解松瘿小卷蛾（Cydia zebeana Ratzebury）发生与林分因子的关系,为控制森林主要病虫危害和提高森林健康提供参考.[方法]通过分析大兴安岭地区93个松瘿小卷蛾受灾小班相关数据研究了松瘿小卷蛾发生与林分因子之间的关系.[结果]主要受灾海拔区间为400 ～630 m,受灾比较严重的3种林型为兴安杜鹃兴安落叶松林、兴安杜鹃白桦林、坡改落叶松林,发病小班数共65个,占发病总数的69.89％.南坡发病数是北坡的2.00倍,郁闭度发病区间相对集中,郁闭度0.40 ～0.70占所有发病总数的87.10％,人工林发病率是天然林发病率的3.84倍,发病林胸径范围主要集中在0～ 16 cm,占受灾林地的93.55％,各胸径组间感病指数差异不显著.虫口密度与发病林地的乔木平均树高、乔木平均胸径均呈显著相关.[结论]为大兴安岭地区森林健康维护与提高提供了技术支撑.[Objective] The relation between forests factors and occurrence of C.zebeana was understand to provide reference for controlling main pests and diseases of forest and improving forest health.[Method] Based on Da Xing＇ an Mountains area of C.zebeana of the affected 93small classes,the relation between forests factors and occurrence of C.zebeana was studied.[Result] C.zebeana infected 93 small classes,in 400-630 m altitude interval.Forests of Xing＇an Rhododendron Xing＇an larch forest type group,Xing＇ an Rhododendron birch forest type group and slope modified larch forest type group were affected by plant diseases and insect pests more seriously of 65 small classes,which accounted for 69.89％ of totality.Southern slope incidence was 2.00 times that of the northern slope,the infected forestry canopy density range was relatively concentrated in 0.40-0.70,accounting for 87.10％ of all disease.Plantations incidence 3.84 times that of the natural forests.Infected forestry DBH mainly concentrated in the range of 0 to 16 cm,which accounted for 93.55％ of the forest.C.zebeana infected index did not significantly correlate with DBH group,but significantly correlated with average tree height and DBH of arbor.[Conclusion] The results provide theoretical basis for the healthy maintaining and improvement of forest in Da Xing＇ an Mountains.
