摘要: 用Renyi及Hill多样性指数簇相结合的方法,对中国寒温带针叶林区域垂直植被的区系多样性、生活型多样性及叶级多样性进行了分析,将亚高山矮曲林带(Ⅰ)、寒温性针叶疏林带(Ⅱ)、山地上部寒温性针叶林亚带(Ⅲ1)、山地中部寒温性针叶林亚带(Ⅲ2)和山地下部寒温性针叶林亚带(Ⅲ3),划分为生物多样性的特殊性植被带(Ⅰ)、过渡性植被带(Ⅱ)及生物多样性的交汇性植被亚带(Ⅲ1)、稀疏性植被亚带(Ⅲ2)和富集性植被亚带(Ⅲ1).对Ⅰ、Ⅱ带及Ⅲ1亚带的植被宜采取保护性经营对策,对Ⅲ2、Ⅲ3亚带,采取恢复和提高其生物多样性,促进植被进展演替的经营对策.

Abstract: By the use of Renyi and Hill's diversity index groups, the plant flora diversity, life type diversity and leaf scale diversity of vertical vegetation in cold temperate coniferous forest region of China were analyzed. Three vegetation zones and three subzones,i.e., subalpine forest zone(Ⅰ), cold temperate coniferous forest zone(Ⅱ),and subzones of cold temperate coniferous forests in upper hill(Ⅲ1),medium hill(Ⅲ2) and lower hill(Ⅲ3) ,are defined as special biodiversity vegetation zone(Ⅰ),transition vegetation zone(Ⅱ),intersected vegetation subzone(Ⅲ1),opened vegetation subzone(Ⅲ2) and aggregate vegetation subzone(Ⅲ1). The protective management strategy should be adopted for Ⅰ,Ⅱ and Ⅲ1 zones. For Ⅲ2 and Ⅲ3 subzones,the management strategy should be to restore and increase biodiversity,and to promote progressive succession.
