贵州江口县野生木本油料植物资源调查与分析

Investigation and analysis of wild woody oil plant resources in Jiangkou county,Guizhou province

为了解贵州江口县野生木本油料植物资源的现状,通过查阅文献、野外实地调查和走访乡民,对江口县2个镇、7个乡的野生木本油料植物资源进行了调查分析。结果表明:该区野生木本油料植物共45科95属158种(含种下单位,下同),其中裸子植物5科10属14种,被子植物40科85属144种;樟科是优势科;山矾属和安息香属是优势属;在区系地理分布上,科以热带性质为主,属以温带性质为主;分布海拔主要集中在400~799 m的范围内;含油部位以种子类最多;用途以制肥皂、润滑油及食用类最多。同时介绍了几种可以优先发展的树种,包括油茶、光皮梾木、木姜子类,并提出一些建议,为今后的开发利用提供理论支持。

In order to understand the status of wild woody oil plant resources in Jiangkou county,Guizhou province,the wild woody oil plant resources of nine towns in Jiangkou county were investigated and analyzed through literature review,field investigation and visiting locals.The results showed that there were158 species(including sub-species,the same below)in 95 genera and 45 families.There were 14 species,10 genera and 5 families of gymnosperms,144 species,85 genera and 40 families of angiosperms.The dominant family was Lauraceae,and the dominant genera were Styrax amd Symplocos.The family of the geographical distribution was mainly tropical,and the genus was mainly temperate.The distribution elevation was mainly concentrated in the range of 400-799 m.Seed was the most oily part and the most use was to make soap,lubricating oil and edible.At the same time,several tree species that could be prioritized were introduced,including camellia oleifera,Cornus wilsoniana and Litsea spp.,and some suggestions were put forward to provide theoretical support for the future development and utilization.
