摘　　要：１９９５年３月１９日，新疆和硕县那音克乡发生Ｍｓ５．０级地震。震前，乌鲁木齐地区地下水中溶解气体Ａｒ、ＣＨ４、ＣＯ２、Ｈ２Ｓ等和库尔勒地区的断层气Ｒｎ相继出现明显的异常。异常具有短期临震性质，主要表现为短期趋势升高，临震突跳。On Mar. 19, 1995,the earthquake with Ms5. 2 occurred in Nayinke township of Heshuo county,Xinjiang. Before the earthquake, the obvious anomalies had appeared in some gases dissolved in ground water in Urumqi region such as Ar,CH4,CO2 and H2S etc.,and also appeared in the fault product gas Rn in Kuerle region. These anomalies have short--impending character. This is primarily shown in two aspects: the gas content tendentiously rose in short term and jumped in impending-term.
