摘　　要：主要在东京城地区樟子松人工林中,针对樟子松枯梢病建立35块固定标准地,并对标准地进行生态环境因子、林分因子、林木营养状况等的综合调查,在此基础上统计分析枯梢病危害与各因素之间的内在联系,通过对病情指数与林分及立地因子相关性分析,得到与病害发生相关性显著的林分立地因子,其中坡向、林龄、土质、混交树种与病情指数相关性显著。另外,修枝、清林、除针、营造混交林等营林措施都对病害发生有明显的抑制作用。The relationship between forest factors and the occurrence of shoot blight of Pinus sylvestris vat. rnongolica was analysed, and the main ecological methods, 35 fixed standard plots have been set up in Dongjingcheng, and the ecology environmental factors, forestry factors and the nutritional status of trees in these plots have been surveyed. The result showed that the main forestry factors of this disease include： slope direction, forest age, soil and the mixed species. And some forests management measures include pruning, liquidation, skimming and building mixed forest can prevent the occurrence of disease.
