摘　　要：为了开发云南省滇池地区的磷资源，对云南滇池湖畔的中尺度环流状况进行了三维数值模拟，模式比较详细地考虑了各种物理过程，模拟结果与实测资料较吻合；滇池区域湖面白天为冷中心，夜间为暖中心；白天的垂直环流比夜间大得多，湖风比陆风影响范围也大得多，系统风对湖风影响较大。Including detailed physical processes, a three dimensional model was used to simulate mesoscale ciculation of the Dianchi lake, Yunnan province.The simulation result was basically accordant with observation data. The area of Dianchi, divided into parts of lakes, mountains, basins and hills, features on a cool center over the lake in daytime and a warm center at night； vertical circulation is stronger in daytime than at night and lake breeze, which is much affected by regime winds, effects much wider influence than land breeze does. It provided some scientific basis for the research of atmospheric boundary layer stracture and crucial reference for enviroment quality assessment.
