摘 要 ：本文分析了马尾松受马尾松毛虫为害后,木材生长的损失情况,提出了一个马尾松中、幼龄单木生长模型,并在此基础上,模拟研究了马尾松受害后损失量的累积过程。结果表明,不同受害年龄,不同受害程度下,马尾松材积量损失明显不同,对于选择不同的防治措施具有重要意义。本文还结合一般化学防治方法,提出了一种防治效益的分析与评价的一般方法。

Abstract:The damage effect of Pine Caterpillar on the growth of Pine tree in wood volume has been studied, A Pine tree growth model has been also developed and used to simulate the influence of the pest damage. It is shown that the wood volume loss may differ at different situations. It depends on the tree age in the damaged year and the degree of leaf damage. General methods for analysing and evaluating the benefit from different management strategies for pest control have been also proposed.
