摘要
对大通县退耕还林中高位山旱地不同配置模式群落物种多样性进行研究。结果表明:不同配置模式的群落物种多样性指标的变化规律明显不同,多样性指数排序为模式H(白桦+青海云杉)>模式J(青杨+中国沙棘)>模式G(华北落叶松)>模式F(青海云杉)>模式K(青海云杉+中国沙棘)。
The species diversity in different figuration model were studied with diversity index in field of converting the land for green project at high and cold mountain region Datong. The results showed that mutative rule on communities diversity index of different figuration model were not same, the order of species diversity index was figuration H〉 J〉 G〉 F〉 K.
