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.
