H " was calculated using the shannon - wiener formula : h " = ? pi ? pi e was calculated using the pielou ' s evenness index e : e = h ' hmax = h ' ? s the results showed that diversity index on different parent materials varied between 0 . 49 to 1 . 02 , the different parent materials followed the sequence of igneous rock > sedimentary rock > metamorphic rock > unconsolidated material ; the evenness index on different parent materials varied between 0 . 27 to 0 . 64 , the parent materials followed the sequence of igneous rock > sedimentary rock > metamorphic rock > unconsolidated material
多样性指数运用shannon指数公式计算，均匀度指数运用pielou指数公式计算。分析结果表明发育于不同母岩上的多样性指数范围为0 . 49 1 . 02之间，从高到低依次为火成岩、沉积岩、变质岩和疏松物质；土壤均匀度指数范围为0 . 27 0 . 64之间，从高到低依次为火成岩、沉积岩、变质岩、疏松物质。
