鄂西南裸子植物资源濒危程度及可持续利用研究

Endangered Degree and Sustainable Utilization of Gymnosperm Resources in the Southwest Hubei

  • 摘要: 2014 年6 月至2016 年5 月,采用线路调查和样地调查方法,对鄂西南裸子植物资源进行了调查。用濒危系数和遗传损失系数定量分析了区域内自然分布的裸子植物濒危程度和急切保护程度,并按用途对裸子植物资源进行了利用分类。结果表明,鄂西南共有裸子植物9 科33 属89 种(含10 变种,12 栽培品种)。其中,乡土树种36 种,占鄂西南裸子植物总种类的40.4%;国家重点保护、国家珍稀濒危、湖北珍稀特有裸子植物分别为12种、10 种、13 种。C 濒,V 急<0.5 的裸子植物分别占区域自然分布裸子植物总种类的33.3%和38.9%,表明鄂西南裸子植物资源整体上受威胁程度较大。鄂西南裸子植物资源的用途分为14 大类,以木材类、观赏类、药用类、纤维类和油脂类5 类植物为主;每种裸子植物有主要用途、次要用途和一般用途之分。根据濒危程度和急切保护程度数值,可制定合理的开发利用措施,为裸子植物资源可持续利用提供了科学依据。

     

    Abstract: Investigations were conducted from June 2014 to May 2016 on gymnosperm resources in the southwest Hubei province, by route surveyand sample plot one. Endangered degree and genetic loss coefficient of the resources were analyzed by endangered index and urgency value, and theirutilization was classified. The results show that there were 89 species of 9 families and 33 genera of gymnosperms in southwest Hubei (including 10varieties and 12 cultivars). Among them, 36 species are endemic, accounting 40.4% of the total species of gymnosperms in the southwest Hubei.There were 12 species under national key protection, 10 species of national rare and endangered, 13 species of provincial rare and endemic.Gymnosperm resources in the southwest Hubei with endangered index and urgency value of less than 0.5 occupied 33.3% and 38.9% of the totalregional natural distribution species, indicating gymnosperm resources in the southwest Hubei was threatened. Gymnosperm resources in the regionwere classified into 14 categories, including wood, ornamental and medicinal. According to endangered degree and the urgency value of gymnospermresources in the southwest Hubei province, recommendations were put forwarded.
