以小兴安岭北部公别拉河流域原生沼泽湿地为研究对象,对不同群落类型进行了植物多样性分析,结果表明:乔木群落多样性指数--白桦-乌拉苔草群丛＞白桦-柴桦-修氏苔草群丛;灌木群落多样性--柴桦-五蕊柳-沼泽皱蒴藓群丛＞细叶沼柳-五蕊柳-修氏苔草群丛＞柴桦-乌拉苔草群丛;草本群落的多样性指数--篷子菜拉拉藤-修氏苔草群丛＞小白花地榆-丛苔草群丛＞大叶樟-修氏苔草群丛＞小白花地榆-修氏苔草群丛.篷子菜拉拉藤-修氏苔草群丛和柴桦-五蕊柳-沼泽皱蒴藓群丛的Shannon-Wiener指数(H')、Simpson指数(D)和Pielou的均匀度指数(Jsi)较高,而白桦-柴桦-修氏苔草群丛和柴桦-乌拉苔草群丛多样性指数较低.
A primordial wetland of Gongbiela River in the north Xiaoxing' an Mountain was chosen as a case study on plant biodiversity analysis of different types of communities. Results indicate that the biodiversity index of tree community is Betula platyphylla-Carex meyeriana > Betula platyphylla-Betula fruticosa-Carex schmidtii; that of shrub community is Betula fruticosa-Salix pentandra-Aulacomnicum palustre > Salix rosmarinifolia-Salix pentandra-Carex schmidtii > Betula fruticosa-Carex meyeriana, and that of herbage is Galium verum-Carex schmidtii > Sanguisorba parviflora (Maxim. ) -Carex cae-spitosa > Calamagrostis langsdorffii (Link)-Carex schmidtii > Sanguisorba parviflora (Maxim. )-Carex schmidtii. As a whole, the Shannon-Wiener index (H'), the Simpson index (D) and Pielou evenness index (Jsi) of Galium verum-Carex schmidtii and Betula fruticosa-Salix pentandra-Aulacomnicum palustre are higher, while the biodiversity indexes of Betula platyphylla-Betula fruticosa-Carex schmidtii and Betula fruticosa-Carex meyeriana are lower.
