摘要
森林可持续经营问题逐渐成为人们关注的焦点 ,而林木群体遗传资源的可持续经营则是其中的重要内容。群体遗传变异信息对群体遗传资源可持续经营具有至关重要的指导作用 ,有关的信息涉及到交配系统、起源与形成历史、群体空间分布形成方式、遗传结构变异分布、地理变异、遗传与环境互作等。这些信息可以用分子标记和适应性数量性状变异来检测。依据这些综合信息可以制定出科学的群体遗传资源保护决策。
Sustainable management of forestry has been becoming a central issue in recent years,while sustainable management of genetic resources is an important part. Information on population genetic variation plays a critical role in guiding sustainable management of genetic resources of tree species. Some relvant theories and their association with sustainable management were discussed in detail in this paper,including mating system,origination and formation of populations,spatial variation,population genetic structure,and the interaction between genotype and environment. Detection of these kinds of information was carried out by using selectively neutral molecular markers and adaptive quantitative traits. Comprehensive use of the information detected by both types of genetic markers can contribute to decision making on conservation of genetic resources,on ideal size of population maintained and on appropriate management for utility in the future.
