摘　　要：为进一步强化对长青管理分局国家重点保护植物红豆杉的保护,对该分局红豆杉资源与分布进行了调查,结果为该区域现有胸径≥5 cm的野生红豆杉718株,分布面积33.41 hm 2,树高1.5~22.0 m、平均6.3 m;胸径5.00~74.84 cm、平均12.91 cm,整体生长状况良好,其中宁陕皇冠山片区种群数量最多,分布面积最大,胸径<5 cm的幼树幼苗2217株;主要以小片状、带状、零星散生等形式,分布在海拔1100~2149 m的次生针阔混交林和落叶阔叶林下,以及半阴半阳坡向的沟谷、河道的两侧坡面、陡坡、崖壁等处,自然更新较差。建议在集中分布区建立保护小区,开展定期监测调查。In order to further strengthen the protection of Taxus chinensis,a survey was conducted regarding the the resources distribution in Changqing management branch.The results showed that there were 718 wild trees of Taxus chinensis with DBH≥5 cm,and the distribution area was 33.41 hm 2,with tree height 1.5~22.0 m,average height at 6.3 m.The DBH was 5.00~74.84 cm,with an average of 12.91 cm,and the overall growth condition was good.The population number and distribution area located in Huangguanshan district of Ningshan were the largest,and there were 2217 seedlings with DBH<5 cm,scattered in the secondary mixed forest of conifers and broad-leaved trees or deciduous broad-leaved forest at an altitude of 1100~2149 m,or in the gully,the slope river sides,the steep slope and the cliff wall of the semi-shade and semi-sunny slope direction.The natural regeneration was poor.It is suggested to establish protection plots in concentrated distribution areas and carry out regular monitoring and investigation.
