| 摘 要： | 从川西高原饮用水赋存的环境-地质条件出发进行研究,较全面的探讨了该区气象、水文、土壤等环境要素对水中氧化还原电位的制约作用.通过对研究区内饮用水赋存环境的一系列环境地质调查与氧化还原电位的现场测试可以得出:(1)该研究区所处特殊的地理位置(青藏高原的东南部一横断山系北段,属川西高山高原区)导致该区具有冬长,无夏,春秋短,气温低,温差大等独有的气象条件;该区主要的构造侵蚀高山地貌类型导致地下水循环具有径流途径短,水力坡度大,水～土间交换作用十分强烈的特点,该区土壤的特点是淋滤作用较强且成弱酸性等,这三个环境要素的特点是直接导致该区饮用水中氧化还原电位值升高的主要原因;(2)由于不同类型水(河水、沟水、泉水、土井水)其与大气接触程度的差异导致其氧化还原值呈现由高到低的趋势,即河水>沟水>泉水>土井水.
