摘　　要：利用滇池流域5个气象站1971-2009年的地面气象资料和昆明气象站2006-2009年探空数据,分析降雨量变化和大气水资源潜力。结果表明,滇池流域平均年降雨量为977.9 mm,2003年以来,降雨量10年滑动平均值呈下降趋势;滇池流域大气水资源潜力较大,5-10月大气水资源潜力在60%以上,11月-次年4月的干旱季节大气水资源潜力为23.8%-72.3%。By using ground meteorological data of 5 meteorological stations from 1971 to 2009 and sounding data in Kunming national basic station,precipitation variation and atmospheric water resource potential was studied. The results show that annual rainfall is 977. 9 mm in Dianchi Lake Basin; Since 2003,10-year running means of precipitation decreased; The atmospheric water resource in Dianchi Lake Basin has great potential. The potential of atmospheric water resource is more than 60% from May to October,the potential of atmospheric water resource is 23. 8%- 72. 3% from November to March of the next year.
