摘要
通过对柴达木盆地的降水量、水气来源、分布规律、年内年际变化规律研究探讨，认为柴达木盆地主要水汽来源为孟加拉湾和印度洋热带西南季风暖湿气流，降水量为115．9mm，属干旱地区。降水趋势由东南向西北、由四周山区向盆地中心逐渐递减，降水年内分配比较集中，年际变化大。
The paper discussas the precipitation, moisture source,distributio and seasonal and yearly variation ofprecipitation in Qaidam basin. The main part of moisture comes from the Bay of Bengal and the tropics warm-wet airsteam ofIndian ocean south-west monsoon. with the precipitation of 115. 9mm and trend gradually decreasing from the south-east tonorth-west and from the meuntain area to centre of the hasin, Qaidam belongs to serious arid region .
