摘 要 ：本文以油松林-油松毛虫生态系统为研究对象,采用系统分析方法,组建了油松生长子模型,油松毛虫种群生长子模型以及油松毛虫危害油松的子模型。并将它们耦联在一起,形成了油松林-油松毛虫系统模型。 为了寻求油松毛虫的优化管理途径,在上述系统模型的基础上,根据油松毛虫的10种常用管理措施的效果和费用,结合危害子模型,组建了油松毛虫的动态经济阈值模型。然后再根据最优化理论,建立了油松毛虫管理决策模型。最后对影响系统的主导因子进行了灵敏度分析。

Abstract:Using system analysis methods, the ecosystem of the Chinese pine--Chinese pine caterpillar (Dendrolimus tabulaformis) was studied and the three dynamics submodels. Chinese pine submodel, Chinese pine caterpillar sub- modle and the damaging submodel of Chinese pine caterpillar were made. For the Chinese pine sasubmodel, the needle leaved weight sub-submodel and dynamic sub-submodels of height growth, diameter growth and wood volume growth were built. For the Chinese pine caterpillar submodel, the ARMQ (p,q) ...
