摘　　要：降水是影响壤中气汞测量结果的重要因素之一。大雨或透雨过后 ,壤中气汞含量急剧降低 ,甚至使异常消失 ;降水量较小 ,有时会使壤中气汞含量显著浓集。Precipitation is one of the important factors affecting the result of soil gas mercurometric survey.Heavy rain or saturating rain would lead to drastic decrease of mercury content in soil gas or even to the disappearance of anomalies.In contrast, when the amount of precipitation is relatively small,the mercury conent of soil gas may sometimes show obvious enrichment.

关 键 词：壤中气汞量测量 降水量 小雨 汞含量 显著富集
