| 摘 要： | 研究理清林木种质资源的概念及调查方法，对做好林木种质资源调查具有积极作用。本研究查阅了大量国内林木种质资源调查的相关文献，结合实际工作经验，分析提出了林木种质资源的广义和狭义概念。结果表明，广义的林木种质资源相当于林木遗传资源或基因资源，主要应用于物种资源保护；狭义的林木种质资源指用于林木品种选育和种苗生产的遗传资源，主要应用于育种和用于种苗生产。针对种质资源的不同概念，并结合当前调查中存在的问题，分别提出了普查和重点调查的目标、对象、方法和技术路线，对尚未开展种质资源普查的地区，提出了具体调查方法选择建议。

| Abstract: | Forest germplasm is an important national strategic resource which are both the core of maintaining biodiversity and the basis for tree breeding and high-quality seedling production.However,the forest germplasm resources survey is relatively backward in China.Some conceptions with germplasm resource are interpreted differently,and the survey methods are not uniform in some areas of China.Therefore,the conceptions and the survey methods should be studied and raveled out.It will have a positive effect for forest germplasm survey.According to the practical experience and a large amount of related literatures,the paper put forwards the broad and narrow conceptions of forest germplasm resource.The forest germplasm resource in broad sense were considered to be equivalent to forest genetic resources or gene resources and mainly used for species resource protection.While the forest germplasm resource in narrow sense referred to the genetic resources used for tree variety selection and seedling production,and mainly used for tree breeding and seedling production.Aiming at different concept connotations of forest germplasm resources and combining with the problems in the current survey circumstances,the objective,content,method and technique routing of general survey and major survey were put forwards respectively.Some suggestions that could be used for the areas where the general survey have not yet be carried out were put forward. |
