摘　　要：大型水电工程的修建将对局地气候产生一定的影响。针对该问题,提出了以地理信息系统(GIS)为支撑,在常规统计模型的基础上,计入大型水库温度效应进行库区气温空间小尺度模拟的修正模型,并在二滩水电站库区进行实际应用。研究结果表明,考虑水库温度效应的修正模型要优于常规统计模型,这为库区任一地域单元气温空间分布的快速计算提供了一种可行的方法,对区域工程设计和水电工程的小气候效应研究具有重要的意义。The construction of large hydroelectric project will lead to local climatic changes. For understanding the spatial distribution of surface air temperature （SAT） in a large hydroelectric project region, a modified multiple regression model is developed to analyze the distribution of SAT in reservoir region. The model is based on geographic information system （GIS） and conventional statistical model and takes into account the influence of the reservoir on SATs in the region. The application of this modified model in Ertan Hydropower Station reservoir shows that the modified model has higher accuracy than the conventional model. The modified model is a feasible method to quickly calculate the spatial distribution of regional temperature and is important to microclimate effect research of regional engineering design and hydroelectric project
