摘要
鳞皮云杉（Ｐｉｃｅａａｕｒａｎｔｉａｃａｖａｒ．ｒｅｔｒｏｆｌｅｘａ）是九寨沟自然保护区针叶林的建群种与优势种之一．从种群的大小结构、种群结构与动态的量化分析以及静态生命表等方面研究了九寨沟自然保护区鳞皮云杉种群的结构与动态特点．结果表明：九寨沟鳞皮云杉种群的大小结构为中间大两头小的纺缍形结构，属增长型种群但增长率不大．
Picea aurantiaca var. retroflexa is one of the constructive species and dominant species of needle leaf forests in Jiuzhaigou Valley Nature Reserve. The quantitative and qualitative methods are used to analyze population of Picea aurantiaca var. retroflexa in Jiuzhaigou Valley Nature Reserve. The results are shown that Picea aurantiaca var. refroflexa is spindle structure and the population is a increasing type, while increasing rate is lower. The population has the characteristics of constant changing.
