| 摘 要： | 对云南松毛虫(Dendrolimus houi Lajonquiere)成灾与14个林分因子进行逐步回归分析，从中筛选出海拔高度、坡向、坡度、开阔度和土壤综合肥力5个关键因子，并用这5个因子建立多元回归模型。从中总结出了虫源地林分和有虫不成灾林分的特点。 |

| Abstract: | In this paper, we make regression analysis step by Dendrolimus houi Lajonquiere and 14 forest factors, from which we select 5 factors such as elevation,slope direction, slope gradient, degree of opening and comprehensive soil fertility as the key factors,and establish the multiple regression model with these 5 factors. By the analysis, we find out the different features of the pest source forest and the forest which has pest,but dosn't cause disaster. |
