摘    要:本文从油松毛虫的优化管理出发,在油松林-油松毛虫生态系统中,将油松林视为一个子系统,通过人工模拟摘叶和油松毛虫自然危害的方法,从宏观上进行了油松生长指标的测定,从微观上进行了油松生理指标的分析,均证明了油松在一定失叶率条件下,具有补偿与超补偿效应。并进一步组建了不同龄级油松的补偿与超补偿模型,同时寻求了相应的补偿点和超补偿点。通过1988—1991年在北京部分地区的应用,有力地说明了该项研究成果具有明显的经济效益和生态效益,可为制定油松毛虫综合防治的新策略提供可靠的科学依据。

关 键 词:油松  油松毛虫  经济阈值

Abstract:From the point of view of the optimal management of Chinese pine caterpillar (Dendrolimus tabulaeformis Tsai et Liu),the ecosystem of the Chinese pine-Chinese pine caterpillar was studied. In the Chinese pine subsystem, using the methods of the artificialy simulative defoliation and of the natural damage to needle leave by Chinese pine caterpillar,the growing index and physiological index of Chinese pine were measured, and Chinese pine proved to have the effects of compensation and super compensation under the conditions of certain defoliation rate.Then the mathematical models of compensation and super compensation of Chinese pine in 4 Age-classes were built and the points of compensation and super compensation were correspondingly obtained.By application in controlling Chinese pine caterpillar in 1988-1991, this study has produced economic and ecological benefits. It provides the reliable scientific basis for developing a new strategy for the IPC of Chinese pine caterpillar.
Keywords:Chinese pine  Chinese pine caterpillar  economic threshold  compensation and super compensation  optimal management
