本文对太白山针叶林植被进行了多元分析，结果表明太白山针叶林可分为６个类型：Ⅰ、巴山冷杉－秦岭小蘖群落；Ⅱ、巴山冷杉－四川忍冬群落；Ⅲ、巴山冷杉－糖茶子－太白花楸群落；Ⅳ、巴山冷杉－太白杜鹃群落；Ⅴ、巴山冷杉－金背杜鹃群落；Ⅵ、太白红杉－头花杜鹃群落。随海拔高度的升高，针叶林的结构组成依次有规律地变化。高位芽植物占４２％、地面芽植物占１２％、地下芽植物占４２％、一年生植物占４％。针叶林的乔木层以幼龄、中龄级占绝对优势，自然更新良好。
The results showed that Taibai Mountain coniferous forest can be divided into six types: Ⅰ, Bashan fir-Qinlingling small tiller community; Ⅱ, Bashan fir-Sichuan honeysuckle community; Ⅲ. Bashan fir - Sugar Chagozeu - Torreya rubashi community; Ⅳ, Bashan fir - Taibai rhododendron community; Ⅴ, Bayesian fir - gold rhododendron community; Ⅵ, Taiga redwood - flower Rhododendron community. With the elevation increasing, the coniferous forest structure changes regularly and orderly. The high bud plants accounted for 42%, ground bud plants accounted for 12%, underground bud plants accounted for 42%, annuals accounted for 4%. Coniferous tree layer to young, middle-aged absolute superiority, a good natural update.
