摘要

苔藓植物在边坡生态系统中有着非常重要的作用

具有涵养水源

保持水土的功能。选择成渝铁路、成昆铁路沿线典型的路堑边坡和自然边坡

对苔藓植物的种类与生物特性的空间变异性以及环境因子进行了调查研究。结果表明

在不同地点苔藓植物种类差异明显。夹江县的试验点苔藓植物共7种

主要以藓纲植物为主

金堂县的试验点苔藓植物共2种

主要以苔纲植物为主。在同-地点

夹江县的试验点苔藓植物种类表现为路堑边坡多于自然边坡

而金堂点路堑边坡与自然边坡苔藓植物种类完全相同。同是路堑边坡

夹江点苔藓植物最大持水率显著大于金堂点。苔藓植物生物量与草本植物盖度、枯落物鲜重呈负相关关系

与土壤硬度呈正相关关系

其中与枯落物鲜重和土壤硬度的相关性达到了极显著的水平。

Abstract

The bryophytes play a very important role in soil and water conservation and water source holding in a slope ecosystem.This paper studies the species

spatial variabilit y

and the environmental factors of the bryophytes on four slopes including railway slope and natural slope along the Cheng-Kun railway and the ChengYu railway.The result shows that the species of the bryophytes are significant!Y.different between the Jiajiang site and the Jintang site.There are about 7 species in Jiajiang site

whereas only 2 species site in Jin- tang site In Jiajiang site

the species of bryophytes on railway slope are more than the species on natural slope

but the species of bryophytes in Jintang site are the same on railway slope and nat ural slope.Largest water holding of bryophytes in Jiajiang is distinctly higher than that in Jintang site.The biomass of bryo- phytes is negatively related to the weight of withered litters.However

the biomass of bryophytes is positively related to soil rigidit y

while there is a negative relation between the biomass of bryophytes and the coverage of herbage.
