摘要
对大通县退耕还林浅山区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不尽相同,群落物种多样性指数排序为模式C>模式D>模式B>模式A>模式E,不同配置模式群落乔、灌、草三层结构物种多样性指数呈现出草本层>灌木层>乔木层的规律。
Biodiversity were studied in different figuration model after converting the land for forestry and pasture in middle hills region of Datong County Qinghai province. The results showed that mutative rule on diversity index of different figuration model were not same, the order of biodiversity index was figuration C 〉 D 〉 B 〉 A 〉 E, and the biodiversity index of arbor, pour and grass three layers took on grass layer 〉 pour layer 〉 arbor layer.
