摘　　要：通过研究异质性生境中淫羊藿克隆构型,初步分析环境因子对淫羊藿克隆生长的影响及克隆构型可塑性对异质性生境的响应。结果表明:生境中相对光强、土壤含水量和土壤有机质含量对淫羊藿的克隆生长影响较大,土壤pH值对其影响较小。建立了淫羊藿克隆构型可塑性特征与环境因子的关系方程。淫羊藿以地下根茎为克隆器官进行克隆生长,在异质性生境中有着较强的克隆构型可塑性。保护淫羊藿地下根茎,以及生境中适当的光照、水分和养分有利于淫羊藿的克隆生长。The responses of clonal architectures of Epimedium brevicornu Maxim to heterogeneous habitats were studied,and the correlations between heterogeneous habitats and plasticity of clonal architectures were explored.The preliminary results showed that the moisture,organic content in soil,and the relative intensity influenced the clonal growth of E.brevicornum greatly in habitat;whereas the value of pH in soil influenced it hardly.E stablished equation about the correlations between characteristics of clonal architectures and habitat factors.The clonal growth of E.brevicornum depended on the rhizome under ground,and the high morphological plasticity of clonal architectures affected by the heterogeneous habitat factors.The rhizome and the appropriate environmental conditions were the essential factors of cloanl growth in the heterogeneous habitats.
