摘要
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 caespitosa 〉 Calamagrostis langsdoorffii （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.
