摘要
经过调查,在盘县发现西康玉兰36株,无幼苗,其分布方式为单株散生分布;植株繁殖以伐后萌蘖为主,缺乏更新层,种群处于衰退阶段。分布在海拔2 200 m以上,位于喀斯特山峰的顶部,地貌类型属玄武岩侵蚀剥蚀地貌。森林生态系统以喀斯特山地森林生态系统为主,土壤为上二叠统玄武岩发育形成的山地黄棕壤。繁殖途径单一、种子萌发率较低、自然环境破坏是导致西康玉兰濒危的主要因素。
Through the investigation,it was found there are 36 strains of Magnolia wilsoni in Panxian County,no seedlings,its distnbution mode for individual scattered distribution; Plant breeding is given priority to with shoot after cutting,the lack of update layer,population decline stage.They are distributed in above 2 200 m,located in karst mountain tops,landform denudation physiognomy type belongs to the basalt erosion.Forest ecosystem is given priority to with karst mountain forest ecosystems,soil for the formation of Permian series on basalt development by mountain yellow brown soil.Breeding way is single,low seed germination rate,the natural environment destruction is the main factor lead to Magnolia wilsoni endangered.
