采用面积调查与抽样调查相结合的方法，对无量山国家级自然保护区云南铁杉的居群分布及结构动态等特征进行了研究。结果表明，无量山国家级自然保护区共记录到20个云南铁杉居群，面积2497.1 hm2；居群的平均海拔分布为2560～2880 m；居群的空间分布格局为聚集分布；胸径5 cm以上的立木分布密度为203.2棵/hm2，立木平均胸径为40.9 cm；绝大多数立木的高度在15～40 m之间；云南铁杉居群属于下降型居群。研究结果对云南铁杉的保护和利用具有重要的参考意义。

Taking area method and sample survey , the distribution and structure dynamics of Tsuga dumosa popu-lations in Wuliangshan National Nature Reserve were studied .Twenty populations were discovered , with the distri-bution area of 2 497.1 hm2 , the average elevation range of 2 560~2 880 m, the spatial distribution pattern was clump.The average distribution density of trees with the DBH over 5cm was 203.2 individuals/hm2 , and the av-erage DBH was 40.9 cm.Most individual ’ s height was 15~40 m, in addition, Tsuga dumosa belonged to decli-ning population .This study provided important reference for the protection and utilization of Tsuga dumosa.
