摘要

为探求淫羊藿资源的保护策略,通过野外样地调查、室内测定和统计分析等方法,对林缘旷地、林缘和林下三种不同生境中淫羊藿(Epimedium brevicornum)克隆构型及其分株种群特征进行了研究,并初步分析环境因子对淫羊藿克隆构型和分株种群特征的影响.结果表明:分枝强度、间隔子长度、分枝高度、根状茎长度及分株种群密度在3种生境中差异显著,且与生境相对光强和土壤含水量有较强的回归关系.群落相对光强、土壤含水量在淫羊藿的克隆生长过程中起着重要作用.淫羊藿以地下根茎为克隆器官进行克隆生长,有着较强的克隆构型可塑性.结合克隆植物对资源的利用策略,讨论不同生境中淫羊藿克隆构型和分株种群特征可塑性的生态适应意义及淫羊藿保护机制.

Abstract：

In order to explore the conservation strategy and resource acquisition of Epimedium brevicornum.The variations of clonal architecture and ramet population characteristics of E.brevicornum growing at the open land of forest edge,forest and forest understory were studied by field investigation and laboratory analysis.The influences of environmental factors on the clonal architecture and ramet population characteristics were analyzed.The results indicated that the branching intensity,spacer length,branching height,length of rhizome and ramet population density were different among three habitats.There were signficant regressive relationships between them and relative light intensity,soil water content of habitats.It implied that the relative light intensity and soil water content of habitats mainly influence the clonal growth of E.brevicornum.The clonal growth depended on the rhizome under ground,and has morphological plasticity.These results were discussed in the context of resource acquisition strategy by clonal plants.The response of clonal architecture and ramet population characteristics to resource heterogeneity has important ecological implication.Protect the rhizome under ground and reduce the disturbance by human being,it's an effectual way to keep the continuable utilization of E.brevicornum which lived in field.
