摘　　要：文章通过对黑河地区过火林地的虫害发生数量和种类的调查研究,表明樟子松和落叶松人工林在火烧后极易受到小蠹类和天牛类蛀干害虫的攻击。利用逻辑斯蒂回归分析表明,树干熏黑高度和胸径对虫害发生数量有一定影响但不是很显著。分别利用树干熏黑高度及其转换后的火强度与虫害发生数量进行一元线性回归分析,结果表明二者与虫害发生数量间的线性关系比较显著,火强度与虫害发生数量的线性关系更显著些。该结论可为火灾之后虫害发生量的预测提供依据。The investigation on the species and amount of the pest in burned forest in Heihe area showed the plantation of Pinus slyvestris var.mongolica and Larix gmelinii were easily attracted by Ips spp.and Anoplophora spp..The relationship between the smoked height and diameter at breast height of poles and the occurrence of the pests was analyzed with binary logistic regression.The result showed there was some logistic relation between them,but not significant.The result of the analysis of the relationship between the smoke height of poles and the amount of the pests with linear regression showed the smoked height of poles had obvious linear relation with the amount of the pests.The conclusion provided basis for the forecast of amount of the pests after forest fire.
