摘　　要：为了准确掌握红豆杉资源在周至县境内的分布情况,为红豆杉资源的保护、管理措施提供本底资料,本文采用样线法对调查区红豆杉资源分布情况、数量和生长状况进行了详细调查。结果表明,调查样线上共分布红豆杉131株,分布海拔770~1 572 m,其中双庙子管护站玉皇庙村、清水河为集中分布区,分布117株,其余调查区为零散分布;调查区红豆杉长势不均衡,株高1.4~11.6 m,胸径1.10~55.72 cm,冠幅0.50~11.30 m。In order to accurately understand the distribution situation of Taxis wallichiana resources in Zhouzhi County and provide background data for the protection and management measures of T.wallichiana resources,this paper particularly adopts the sample line method to investigate the distribution,quantity and growth of T.wallichiana resources in the survey area.The results show that 131 T.wallichiana were distributed on the survey line area at an altitude of 770~1572 m.Especially distributing in Yuhuangmiao Village and Qingshui River,totally 117 were collected in the survey area.The remaining survey areas were scattered,the growth condition of T.wallichiana in the survey area was unbalanced,with plant height of 1.4~11.6 m,DBH 1.10~55.72 cm and crown width of 0.50~11.30 m.
