摘要
对杭州西湖山区常绿阔叶林(EBLF)、落叶阔叶林(DBLF)和针叶阔叶混交林(NBLMF)3种植被类型的群落多样性指数进行比较。结果表明:落叶阔叶林具有较高的物种多样性,针叶阔叶混交林物种多样性较低;在垂直结构物种多样性比较中,常绿阔叶林和针叶阔叶混交林为灌木层〉乔木层〉草本层,而落叶阔叶林为灌木层〉草本层〉乔木层;枯立木在常绿阔叶林中主要存在于6~10m高度,而落叶阔叶林和针叶阔叶混交林中主要存在于3~4m高度。与其他各地植被类型相比,常绿阔叶林和落叶阔叶林群落物种多样性随纬度增加而减少。
Diversity indexes of plant communities in three vegetation types of the West Lake hills, Evergreen Broad-Leaved Forest (EBLF) ,Deciduous Broad-Leaved Forest (DBLF) and Needle and Broad-Leaved Mixed Forest (NBLMF) , were compared. Results show higher plant community diversity in DBLF and lower diversity in NBLMF. Diversity indexes of different forest layers in EBLF and NBLMF are in the following order: shrub layer 〉 tree layer 〉 grass layer; and shurh layer 〉 grass layer 〉 tree layer in DBLF. Dead trees are 6 m to 10 m high in EBLF and 3 m to 4 m high in DBLF,and NBLMF. In comparison with other vegetation belts,community diversity index decreases with increase in latitude in EBLF and DBLF.
