摘　　要：采用典型群落样地调查法,对新疆喀纳斯旅游区森林群落乔木层物种多样性特征进行了研究。结果表明:喀纳斯旅游区森林群落类型多样,不同类型的森林群落乔木层具有不同的物种多样性。处于演替前期和后期的阔叶林和针叶混交林群落物种多样性均较低。以针叶树种和阔叶树种混交的森林群落乔木层物种多样性均较高,基本上处于演替的中期,是喀纳斯旅游区分布较为广泛的森林群落类型。This paper studied characteristics of arboreous species diversity among different forest community types in Kanas tourism district, Xinjiang by typical community sampling plot method. The main results showed that forest community types in Kanas tourism district was complicated and various. Different forest community types have different arboreous species diversity. Community species diversity of broadleaf forest and conifer mixed forest situated at prior succession stage or at later succession stage was lower. Community species diversity of forest mixed with broadleaf and conifer in Kanas tourism region was higher, which basically situated at intermediate succession stage and also were distributed widely in Kanas tourism district.
