【摘要】 为查清浙江省白豆杉资源状况,应用典型抽样的原理对浙江省白豆杉分布面积、数量、生境、植物区系及群落特点等进行实地的样方调查。调查得知,浙江省白豆杉有11个分布点,根据29个样方的调查资料推算,浙江省白豆杉的资源总量为24.22万丛,分布面积为408.08hm2;通过对资料的整理分析,浙江省白豆杉群落的植物区系具有起源古老,珍稀植物较多,地理成分复杂,并具有明显的过渡性等特点;其群落类型属于4个植被型,8个群系组,11个群系类型,白豆杉的生长分布与其所处生境和伴生种猴头杜鹃存在着密切联系。
【Abstract】 To make a thorough investigation of Pseudotaxus chienii (Cheng) Cheng in Zhejiang Province, distribution amount, habitat of this plant and the flora and community features of areas where they grow were studied, which was based on the principle of typical sampling. Our results showed that there were 11 distributive populations in Zhejiang. According to analysis on data from 29 quadrates, the total resources of P. chienii amount to 242.2 thousand clumps, the distributive area cover 408.08 hm2 and the communitytypes are comprised of 4 vegetative types, 8 formation groups and 11 formations. It is also shown that the flora of the communities of P. chienii is of ancient origin associated with complex geographical elements and characterized by some conspicuons transient features. Habitats of P. chienii has been found to be closely related to its ecological environments and its accompanying species Rhododendron simiarum.
