禄丰县思茅松毛虫成灾与林分因子相关性调查研究

A Study on the Relationship between Forest Factors and Outbreak of Dendrolimus kikuchii in Lufeng County,Yunnan Province

  • 摘要: 对思茅松毛虫成灾与 1 4个林分因子进行逐步回归分析,从中筛选出主层林郁闭度、林木生长势、坡向和海拔高度 4个关键因子,并用这 4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: The relationship between outbreak of D. kikuchii and fourteen forest factors was analysed by a stepwise-regression method, and that crown density, potential of growth, slope aspects and altitude were selected out as the last four key factors.A multiphase linear regression model was made by using the four key factors.The characteristics of the pest-source stand and the stand with pests but without disaster have been summarized.
