摘　　要：在新疆沙尘暴主要发生区布设了22个大气降尘观测点,对2007年春夏季大气降尘总量进行监测。分析表明:南疆大气降尘总量远高于北疆,塔里木盆地的高值中心位于盆地偏南部;将大气降尘与气象要素进行相关分析,表明大气降尘与降水量呈负相关关系,大气降尘与沙尘天气发生日数存在正相关关系。The 22 observation stations were set up to monitor the total dust fall in spring and summer. Thy were located in the sand-dust storm frequently happenning area in Xinjiang. Analysis to the data in 2007 showed that the total of dust fall in south of Xinjiang is higher than that in north of Xinjiang; the higher nu- merical value center of Tarim Basin is located in south of the basin. Correlation analysis found a negative correlation between total dust fall and precipitation, and a positive correlation between total dust fall and days of sand-dust weather.
