摘　　要： 包括河流、小型景观湖泊等在内的城市水体表面与城市大气之间的热湿交换是影响城市局地热湿气候的重要因素之一。本文以某国际商务城规划项目为研究对象,进行了包括城市水体及周边复杂建筑群落在内的CFD三维计算模拟,模拟中导入了水体表面与大气之间热湿交换的简易计算方法并考虑了太阳辐射影响。通过CFD模拟对城市水体周边风场、湿度场和温度场分布进行了分析评价。模拟结果表明,城市水体本身的形态分布和水体周边的建筑高度和布局对局地热湿气候的影响很大。 As one of the important influence factors of urban climate, urban water bodies, including urban river and small landscape lakes, have effects on local thermal and moisture climate, in which the transportation of heat and water vapor between water surface and atmosphere is the main reason. In this paper,taken an international business park planning project as the research object,a three-dimensional CFD simulation including urban water bodies and surrounding building complex was carried out. In this simulation, the simple computational method of heat and moisture exchange between water surface and atmosphere was introduced and the effect of solar radiation was considered. The fields of wind ,temperature and relative humidity around the urban water bodies were evaluated. The results indicated that the distribution of the river, the height and layout of surrounding buildings had important influences on local tbermal climate.
