摘　　要：调查和分析钱江源-百山祖国家公园百山祖园区红豆杉、南方红豆杉和白豆杉资源分布及群落组成特点,为其合理保护与开发利用提供依据。采用样方法对百山祖园区的红豆杉、南方红豆杉和白豆杉资源分布进行全面调查,掌握其种群数量、分布格局、生境及居群状况。结果显示:百山祖园区红豆杉、南方红豆杉和白豆杉分布点共31个,覆盖3个乡镇街道。红豆杉种群植株数量相对较多,水平分布跨度较大,垂直分布差可达1 000 m,多分布于村旁风水林或人为干扰较少的保护区,主要伴生树种为壳斗科、柏科和蔷薇科树种。南方红豆杉多以古树存在于村落周边,均分布在海拔1 000 m以下,人为干扰较大,主要伴生树种为壳斗科、柏科和蔷薇科树种。白豆杉种群数量极少,都分布在海拔1 100 m以上的保护区,主要伴生树种为壳斗科和杜鹃花科树种。调查结果表明:百山祖园区红豆杉、南方红豆杉和白豆杉野生资源稀少,亟需保护,人为活动频繁及自身生长特性是导致其濒危的主要成因。To investigate and analyze the resource distribution and community characteristics of Taxus wallichiana var.chinensis,T.wallichiana var.mairei and Pseudotaxus chienii in Baishanzu Park,Qianjiangyuan-Baishanzu National Park,and provide the basis for rational protection,development and utilization of related resources.The resources of T.wallichiana var.chinensis,T.wallichiana var.mairei and P.chienii in Baishanzu Park were investigated by using sample method,and the population quantity,distribution pattern,habitat and population status were obtained.There were 31 distribution points of T.wallichiana var.chinensis,T.wallichiana var.mairei and P.chienii in Baishanzu Park,covering 3 township streets.The number of T.wallichiana var.chinensis population is relatively large,the horizontal distribution span is large,the vertical distribution difference is up to 1000 m,mostly distributed in Feng-shui forest near the village or the protected area with less human interference,and the main associated tree species are from Fagaceae,Cupressaceae and Rosaceae.Most of T.wallichiana var.mairei exist around the village as ancient trees,all of which are distributed with altitude below 1000 m,with great human interference.The main associated tree species are from Fagaceae,Cupressaceae and Rosaceae.The population of P.chienii is very small,distributed in the forests of protected area with altitude above 1100 m,almost without human interference,and the main associated tree species are from Fagaceae and Ericaceae.The wild resources of T.wallichiana var.chinensis,T.wallichiana var.mairei and P.chienii in Baishanzu Park are scarce and need to be protected.The frequent human activities and the growth characteristics of three tree species are the main causes of its endangerment.
