摘　　要：通过采用营林卫生伐措施,清理遭受病虫危害的松树病枯死树、衰弱木、被压木、枯枝等,分析比较常年清理、集中清理和不清理等不同处理方式对松墨天牛成虫种群数量动态和松病枯死树数量变化情况的影响。结果表明:经3a的处理,3种处理方式对松墨天牛成虫种群数量动态和松病枯死树数量变化差异明显。其中,松墨天牛成虫虫口减退率和防治效果分别为:常年清理为94.09%和94.62%、集中清理为52.82%和57.03%,不清理天牛成虫虫口数量增加9.91%;松病枯死树减退率和防治效果分别为:常年清理为100%和100%、集中清理为69.28%和86.53%,不清理松病枯死树数量增加128.02%。In this paper,sanitation cutting had been adopted to clean up the pine trees,which were disease-suffered,dead,weak and pressed,including dead branches,etc.we had analysised and comparison of Monocha-mus alternatus population dynamics and the number of dead and suffered pine tree changes by differenttreatments,such as whole- year- cleaning- up,centralized- cleaning- up and non- cleaning- up.The resultsshowed that,after 3 years,there are significant difference of quantity change of Monochamus alternat-us adult population dynamics and pine dead and suffered tree by 3 kinds of treatment methods.The de-crease rate and control effect of population of pine sawyer beetles were：the decrease rate and control ef-fect of dead and suffered pine tree were：whole-year-cleaning-up is 100% and 100%,centralized-cleaning-up is 69.28%和86.53%,non-cleaning-up is increase of 128.02%.
