红皮云杉种质资源现状及保存策略

Current Status and Strategies for Conservation of Germplasm Resources from Picea koraiensis

红皮云杉(Picea koraiensis)是中国北方云杉属(Picea Dietr.)植物中珍贵的暗针叶林树种,综合利用价值较高。笔者对红皮云杉的起源与进化、地理分布、资源现状、生态环境、生态耦合性、变异趋势、遗传效应及综合利用价值进行了系统全面的分析与总结,并根据目前的资源利用趋势和濒危现状,提出中国东北寒地种质资源保护及开发利用的主要策略。旨在为红皮云杉种质资源的有效保存与可持续利用提供科学依据。

Picea koraiensisis the precious trees of dark coniferous forest in Piceaspecies,which it hold higher utilization value.The origin,the geographic distribution,the status of resources,the ecological environment,the ecology coupling,the tendency of variations,the genetic effects and the comprehensive utilization value were given systematic and comprehensive analysis and summary.Then,the main strategies were put forward to protect and comprehensively exploit the resources which distributed in the cold region of Northeast China,according to the trend of utilization and the endangered status.All of these efforts were orientated for the purpose of conversation and sustainable exploitation of germplasm resources fromPicea koraiensis.
