摘要
通过对林木蛀干性害虫的发生情况和林木的健康程度的调查研究,分析了森林亚健康与蛀干性害虫之间的互动关系,结果表明,一些蛀干性害虫是导致森林亚健康的诱发因素,而处于亚健康状态的林分又会引发另一些蛀干性害虫的危害,从而加速森林的衰退。维护森林的健康,应根据不同森林类型和经营目的分类施策。
A survey on occurrence status of trunkborer-insect and healthy condition of forests was conducted in order to study the relationship between sub-healthy forest and trunkborer-insect. Some trunk borers resulted in sub-health of forest, while the sub-healthy forest would be damaged by other trunk borers, which accelerate forest decline. Corresponding tactics should be implemented according to different forest types and management objects in order to maintain forest health.
