摘要
马比木是富含喜树碱的木本药用植物,具有多种生理功效。采用样地和走访相结合的方法,对湖南湘西州的马比木资源现状进行了调查。结果表明:马比木在湘西州8个县市均有分布,主要分布在海拔900 m以下的山谷、灌丛、林间等荫凉的生境。马比木所在的植物群落结构由乔木、灌木、草本组成,样方中以岩木瓜、光叶海桐、十大功劳等为优势种。由于肆意采挖,湘西的马比木分布区域中的种群密度骤然减小,储量降低,资源量仅约为51.63 t,已濒临灭绝。根据调查结果提出了对野生马比木资源的保护措施和管理对策。
The woody medicinal plant Nothapodytes pittosporoides is rich in camptothecin which has various physiological functions.The status quo of Nothapodytes pittosporoides resources in Xiangxi Autonomous Prefecture of Hunan province was surveyed by plot investigation and interview investigation.The results showed that Nothapodytes pittosporoides distributed in the shady habitats of valley,shrub and forest,which located the altitude that below 900 m,in all eight countries of Xiangxi Autonomous Prefecture.The structure of plant community including Nothapodytes pittosporoides was consisted of arbor,shrub and herbage.Ficus tsiangii,Pittosporum glabratum and Mahonia bealei were dominant species in the plot.The population density and reserves of this medicinal plant had descended dramatically in this area for excessive digging.The total resource reserves of Nothapodytes pittosporoides only has 51.63 ton,it is in an endangered situation now.So,the protective and managing measures for wild Nothapodytes pittosporoides resources were put forward in the end.
