摘　　要：利用张掖两套自动气象站2017年逐小时气温、本站气压、10 min风速和地面温度观测数据,按照数理统计方法对数据在不同的数值区间进行缺测率、差值平均值、标准差、一致率和超差率的对比分析,并利用偏度和峰度系数分析了差值的分布特征。结果表明:气温和10 min风速的差值平均值和一致率较好,而地面温度和气压的一致率较差,地面温度在40℃以上的超差率非常大,差异原因与双套自动站型号、数据采集时间、地温场下垫面、安装维护和仪器更换有密切关系。建议双套站主采设备装备为同一型号,地面温度用4支替代现有的单只铂电阻地温传感器。The paper focus on the two sets of automatic meteorological station of Zhangye national climate stations in 2017, punctual record of air temperature, relative humidity, air pressure, wind speed of the station for ten minutes and the ground temperature data missing rate, the difference of average value, standard deviation, consistency and comparative were collected. Having gone through the data, it is found that the average and consistent rate of the difference of temperature, relative humidity and wind speed for ten minutes is better, and the consistent rate of ground temperature and air pressure is relatively poor. and the ground temperature over 40 degrees is very large. The difference is closely related to the model of double automatic station, the time of data collection, the surface of the ground temperature field, the installation and maintenance and the replacement of the instrument, h is suggested that the main equipment of the dual station is the same type, and the ground temperature should be replaced by four existing single platinum resistance geothermal sensors.
