摘　　要：鸣沙山月牙泉是世界上罕见的沙漠景观。近年来,月牙泉水位不断下降,呈现干涸趋势。通过实地考察和数据资料的比较分析研究,得到月牙泉水位下降的原因:自然因素(新构造运动、水面蒸发、全球变暖、风沙淤积)和人为因素(水利工程建设、地下水的开采利用、旅游业的兴起),并对此提出措施:治标(灌坑式重点渗水工程、重点地段重点配水、渗补工程、党河旧河床远补措施、节水性灌溉措施)和治本(合理开发利用党河流域水资源、祁连山雪山融水、“引哈济党”,解决区域用水水源问题)。The Sing Sand Mountain and Crescent Moon Spring is a rare desert view in the world. In recent years, the Crescent Moon Spring descends continuously, presenting the dried up trend. Through on-the-spot investigation and the comparison analysis research of the data, the decadent reason of Crescent Moon Spring is as follows. Natural factor （neotectonic movement, surface evaporation, global warming, the sandstorm silt-up） and artificial factor （hydraulic engineering construction, groundwater exploitation and use, the rising of the tourism industry）. The countermeasures are put forward as follows. Infusing the pit infiltration water engineering,allocating water to the point district,infiltration to repair the old river bed engineering of the Pong River, the water-saving irrigation measure,and the reasonable use of the Pong River＇s water resources, and snow-melting water of Qilian Mountain,diverting the Ha River to Pong River, resolving the water resource problem of the district.
