摘要:
采用走访和实地调查相结合的方法对云南野生琴叶风吹楠进行资源调查。结果表明:琴叶风吹楠在云南分布于热带雨林内水热条件较好地段,由于生境破坏,种群数量锐减,仅在分布区边缘的沟谷和低洼地呈斑块状分布,种群数量小;琴叶风吹楠现存植株开花结实和种子萌发正常,而且苗木生长良好。生境破坏是导致种群数量锐减的主要原因之一。建议加强原境保护力度和人工辅助繁殖扩大种群数量,同时收集各地种源集中保存以促进基因交流,并开展资源发展利用以实现资源保护。
Abstract:
Survey on wild resource of Horsfieldia pandurifolia in Yunnan was conducted via field investigation and interview investigation. The results showed that H.pandurifolia was an important species in tropical rainforest. Due to ecology destroy,the resource of H.pandurifolia has been reducing,a small quantity of individuals survived only at isolated valleys. H.pandurifolia has well biology characteristics including blossom,fructification,seed germination and growing characteristics at the stage of seedling. Ecology destroy was one of the main causations which result in population depression of H.pandurifolia. It is suggested that active methods including in situ conservation,ex situ conservation combined with provenance collection and resource development combined with utilization should be adopted for protecting resource of H.pandurifolia.
