<正>在对森林生态系统健康理论的发展历程进行回顾的基础之上，对森林生态系统健康理论的内涵以及恢复与重建等内容进行了系统论述。在对国外森林健康实践的现状进行总结的基础上。指出影响森林健康的主要因素有人类活动、森林生境的简单化与森林系统的破碎、森林经营管理方式、自然干扰因素、外来生物入侵、环境污染以及森林生物的危害等。针对我国森林生态系统的结构、功能和演变的现状、健康状况和林业生态建设宏观战略目标，指出了我国森林健康应该在营造和重建环节、改造和恢复环节、生产经营和利用环节、防止林业生物入侵等方面进行有针对性的研究实践。同时实施森林有害生物的可持续控制，提高森林生态系统免疫能力；预防控制空气污染和森林防火。减轻环境因素对森林生态系统的破坏。

22 geographical populations of Anoplohora glabripennis and 1 species of A. chinensis, covering 16 regions in China, 2 regions in USA and 2 regions in South Korea were collected. Those specimens were screened for polymorphic RAPD markers with 17 arbitary primers. There were totally 219 different polymorphic loci obtained, which were sufficient to identify the differences of DNA at the intra-specific and inter-specific levels among these populations studied. According to the relationships of genetic distances in RAPD phylogram, Anoplohora was classified into a clustering branch, geographical populations of A. glabripennis were classied into another clustering branch. In RAPD phylogram, the population of A. glabripennis in USA was classified into an indpendence clustering branch, which showed that the origin of A. glabripennis distributed in USA was not likely from China.
