摘　　要：水曲柳是东北三大珍贵硬阔叶用材树种之一,第三纪孑遗植物。现在处于濒临灭绝的状态,必须采取有效的措施来加以保护。从地理分布、生长规律、繁殖方式、遗传改良、造林技术等方面对水曲柳的研究进展进行了综述,在此基础上,提出了水曲柳基因资源保存与利用策略:重视水曲柳遗传资源的收集和保存;加快快繁技术及推广应用研究;制定系统的育种策略和高世代改良计划;开展遗传变异和遗传多样性的研究,以实现资源的合理利用和可持续发展。Fraxinus mandshurica is one of the precious three broadleaved tree species in northeast of China, a tertiary survival plant. At present it is on the verge of extinction, so effective measures must be taken in order to protect it. This paper introduced the research development of Fraxinus mandshurica from the aspects of distribution, growth rule, propagation technology, genetic improvement, forestation technology, and on the basis of that, the tactics were provided. We paid attention to collect and protect the gene resources, accelerate the study on propagation technology, establish bleeding strategy, high generation improvement program, and research on the genetic variation and genetic variety, and in order to realize rational utilization and sustainable development of plant resources.
