基于遗传多样性分析的海洋保护区典型物种保护措施研究——以山东昌邑国家级海洋生态特别保护区柽柳为例

Protection Measures for Typical Species in Marine Protected Areas Based on the Analysis of Genetic Diversity:Take Tamarix chinensis in Shandong Nearby National Special Marine Reserve as an Example

遗传多样性是评价自然生物资源的重要依据,可为遗传资源保存、育种、遗传改良以及制定物种保护措施等工作提供理论支撑。山东昌邑国家级海洋生态特别保护区是全国唯一的、以柽柳林生态系统为主要保护和管理对象的国家级海洋特别保护区。文章利用ISSR分子标记技术,对30个柽柳个体的遗传多样性进行分析,并根据分析结果提出避免从外区域移栽、控制人类活动和开展遗传多样性研究等保护措施,为深入了解该保护区典型保护物种柽柳的遗传结构、多样性、种质资源以及制定合理有效的生态系统保护策略提供理论依据。

Genetic diversity is the important basis for evaluation of natural biological resources,which can provide theory support for conservation,breeding and genetic improvement of genetic resources,as well as making protection measures to protected species.Shandong nearby nationalmarine ecological special reserve is the only national marine protected areas taking tamarix as the main object of protection and management.The genetic diversity of 30 tamarix samples were analyzed by using ISSR molecular markers,to understand the genetic structure,diversity,germplasm resources and corresponding protection measures of avoiding transplanting from outside areas,controling human activities and carrying out genetic diversity research,according to the results.It also will provide theoretical basis to formulate rational and effective ecosystem protection strategies.
