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，分析比较长年清理、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。结果表明：经3年的处理，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。松墨天牛成虫虫口减退率和防治效果分别为：长年清理为94.09%和94.62%、集中清理为52.82%和57.03%，不清理（CK）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：长年清理为100%和100%、集中清理为69.28%和86.53%，不清理（CK）松病枯死树数量增加128.02%。
通過採用營林衛生伐措施，清理遭受病蟲危害的鬆樹病枯死樹、衰弱木、被壓木、枯枝等，分析比較長年清理、集中清理和不清理等不同處理方式對鬆墨天牛成蟲種群數量動態和鬆病枯死樹數量變化情況。結果錶明：經3年的處理，3種處理方式對鬆墨天牛成蟲種群數量動態和鬆病枯死樹數量變化差異明顯。鬆墨天牛成蟲蟲口減退率和防治效果分彆為：長年清理為94.09%和94.62%、集中清理為52.82%和57.03%，不清理（CK）天牛成蟲蟲口數量增加9.91%；鬆病枯死樹減退率和防治效果分彆為：長年清理為100%和100%、集中清理為69.28%和86.53%，不清理（CK）鬆病枯死樹數量增加128.02%。

In this paper, sanitation cuttings had been adopted to clean up the pine trees, which were disease-suffered, dead, weak, and pressed, including dead branches, etc. We had analyzed and compared population dynamics of Monochamus alternatus and the number of dead and disease-suffered pine tree changes by 3 different treatments, such as whole-year-cleaning-up, centralized-cleaning-up and non-cleaning-up. Results showed that, after 3 years, there were significant differences of quantity changes of Monochamus alternatus adult population dynamics, dead and disease-suffered pine trees by 3 treatment methods. The decrease rates of population of pine sawyer beetles and the control effects were:whole-year-cleaning-up were 94.09%and 94.62%, centralized-cleaning-up were 52.82%and 57.03%, and non-cleaning-up (CK) increased by 9.91%. Besides, the decrease rates of dead and disease-suffered pine trees and the control effects were:whole-year-cleaning-up were 100% and 100%, centralized-cleaning-up were 69.28% and 86.53%, and non- cleaning-up (CK) increased by 128.02%.
