| 摘 要： | 油松毛虫(Dendrolimus tabulaeformis)是我国华北地区油松林的重要害虫之一。其分布面积广、发生频繁、危害严重。有人曾对油松毛虫种群的生物学特性、防治以及种群动态的研究作过有关的报道,本文则通过对油松毛虫的数量变动进行跟踪调查,并用Leslie矩阵模型对其种群动态进行了模拟,这对害虫的测报具有重要的实践意义。一、材料与方法 (一)标准地概况 1984—1986年与1988—1989年我们分别在密云县五座楼场和石墙沟村选择了5块油松纯林作为标准地,概况列在表1中:

| Abstract: | According to the researches on the population dynamics and effective accumulated temperature of Dendrolimus tabulaeformis, a Leslie matrix model of this pest insect is established. After the vector of population on some time are imputed, the development of the population can be showed. the simulation results basically fits what occurred in the field. |
