摘  要:
影响油松毛虫种群数量的主导因子有5个,即:山形、坡度、坡向、土壤质地和山的开阔度。根据油松林分立地类型不同,松毛虫发生量也不同的情况,划分出3种立地类型及其相对应的松毛虫发生量林分,采取相应的对策控制松毛虫危害。

摘  要:
Five main factors influencs population dynamic of Dendrolimus tabulaeformis are mountain form,slope,aspect,soil texture,width of hill.Population dynamics of pine caterpillars is different with different site types of Pinus tabulaeformis plantation.We divided 3 kinds of site tpyes compared with the corresponding pine caterpillars' dynamics stand and took corresponding measures to control pine caterpillars.
