| Abstract: | some management measures,such as forest land cleaning,isolation belt opening and stand transformation, had significant function of decreasing damage of Monochamus alternatus.forestland cleaning could decrease density of Monochamus alternatus population by 91.0%;isolation belt could effectively prevent Monochamus alternatus from naturally diffusing; local stand transformation could decrease damage rate of forest by 55.7%. |
