摘　　要：象山国家基本气象站于2018年1月1日由城区搬迁至郊区。本文通过对比新旧两站2018年至2022年的气温资料,得出了如下结论:两站具有相似的年际变化、月变化及日变化。两站年平均气温基本持平,旧站年温差大于新站;新站的年平均最低气温恒大于旧站,但新站的年平均最高气温恒小于旧站;从各季节特征月来看,一月和十月新站日平均气温高于旧站,四月和七月新站日平均气温低于旧站。日平均气温差值最大值多出现于气温最高的时次;新站对于象山城区的高温预警方面代表性较差。The Xiangshan National Basic Weather Station was relocated from urban to suburban areas on Jan-uary 1, 2018. By comparing the temperature data of the old and new stations from 2018 to 2022, the following conclusions are drawn: The two stations have similar inter-annual, monthly, and daily variations. The annual average temperature of the two stations is basically the same, and the annual temperature difference of the old station is higher than that of the new station;The annual average minimum temperature of the new station is always higher than that of the old station, but the annual average maximum temperature of the new station is always lower than that of the old station. From the perspective of the characteristic months of each season, the average daily tempera-ture of the new station in January and October is higher than that of the old station, and the average daily temperature of the new station in April and July is lower than that of the old station. The maximum daily average temperature difference occurs when the temperature is the highest;The new station is poorly represented in terms of high temperature warning in Xiangshan urban area.
