摘　　要：利用四川近年台站迁移新旧站址对比观测资料,采用统计检验方法,对新旧站址观测资料进行对比评估。结果表明:迁站后观测环境得到改善,热岛效应影响减小,气温降低,相对湿度和风速升高。迁站对气温极值的影响大于平均值,对降水、相对湿度和风向的影响较大,新旧站址的风向一致性较差。由于旧站址遭受破坏的程度,周边障碍物的存在形式、所处方位、距离、下垫面状态及迁移距离、高差等的不同,造成对气象要素的影响程度会不同,从而造成迁站对各站及各要素影响的差异。Using the method of statistics test to make comparative evaluation of the old and new station＇ s observational data, which observed in Sichuan recent years. The results showed that moved to the new station have improved the observation environment, reduced the influence of heat island effect and the temperature observation value, but also increased the relative hu- midity and wind speed of observations. The influence to extreme temperature was greater than average temperature. The precipitation, relative humidity and direction had large influence, and wind direction had poor consistency. Due to the extent of the damage to the old station, surrounding obstacles form of existence, a prescription, distance, the underlying surface condition , migration distance and height difference of different, led to the different influence of the meteorological elements, and the different influence to each moved station.
