摘要(Abstract)：

[目的]研究毛乌素沙地与植被有关的地下水环境。[方法]选择毛乌素沙漠腹地,研究沙漠地区植被与地下水的关系,建立了沙漠地区的研究植被与地下水关系的指标体系,即植被的种群、地下水埋深、包气带含水率、地下水矿化度和包气带含盐量等,以及相应的野外工作方法。[结果]结果表明,研究区分布有9个主要的植被种群,沙蒿(Artemisia)、沙柳(Salixpsammophila)和苔草(Carex)是优势植被;地下水矿化度在沙丘地区为100～300mg/L,滩地为800mg/L左右;包气带含水率全年维持在8%～16%;沙丘含盐量小于0.2%,滩地含盐量大于0.3%。[结论]这些成果为研究该区植被与地下水的关系提供了依据。
