摘要
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。
In this paper, the coniferous forests in Taibai Mountain were multivariately analysed The results show that the coniferous forests can be classified into 6 types: I form, Abies fargesii-Berberis circumserrata; Ⅱ form, Abies fargesii-Lonicera szechuanica;Ⅲ form, Abies fargesii-Ribes emodence-Sorbus tsinlingensis, Ⅳ form, Abies fargesii-Rhododendron purdomii;Ⅴform,Abies fargesii-Rhododendron clementinae, Ⅵ form, Larix chinensis-Rhododendron capitatum The structure and component of the coniferous forests in Taibai Mountain regularly varies with altitute increasing The phanerophytes occupy 42%, the hemicrytophytes 12%, the cryptophytes 42% and the therophytes 4% in the coniferous forests The young and middle trees are dominant in the coniferous forests and alternate well
