摘　　要：海南粗榧的根、茎、叶、皮和果实都含有生物碱，具有较强的抗癌功效。由于它本身是一种残遗植物，天然更新能力差，分布数量有限，加以遭到过度的砍伐，已陷入灭绝的边缘。本文通过论述其地理分布、生物生态学特性、栽培技术，分析其濒危原因，提出保护措施，期待把其从灭绝边缘挽救过来，提供更多的资源。The Hainan plumyew is a relict species. In one hand, owing to its own low reproductive capacity, numbers of individuals are not much in wild condition:and in other hand, because it has important economic value, always was cut for use, its individuals are more and more decreased, the regarded habitats caused by destroying forests make a notable impact on its regeneration and rehabitilation.Therefore, it has been fallen into endangered condition. If it does not take Suitable conservational measures, it will be extincted. Although some protected areas have been established in its concentrated distributional areas in Hainan island,but it is difficult to avoid evasive cutting. So it is necessary to strengthen works of ex-situ conservation, and to set up artificial cultivated bases both from view point of conservation and sustainable use in order to satisfy actual requirement.
