摘要
森林害虫的科学管理必须考虑长远的经济效益和社会效益问题,只有对森林害虫进行生态控制才能达到森林可持续经营的目的。在人工林构建中,只有模拟天然林结构,从害虫原栖息地抗虫林分结构出发,才能从根本上解决猖獗成灾问题。在对黑龙江省主要造林树种的天然抗虫结构、人工混交林和人工纯林的结构及害虫发生情况进行对比分析的基础上,提出了人工林害虫生态控制策略。
The scientific management of forest pest must account for long economic and social effects, and aim at the forest sustainable management by ecological controlling for forest pest. As long as the plantation simulate for forest structure and take use of the component of anti - insect in its habitat, we can solve the problem for pest disaster. This paper put out the strategies of ecological control pest on the basis of analysis for anti - insect structure of main tree species, the structure and pest of mix and pure plantations.
