Abstract：Through the comparison analysis and test of part meteorological elements achieved from Zhangye national basic weather station from 1971 to 2012 before and after moving station,it found that the regional consistency of the annual average temperature,relative humidity and wind speed data is poor,and the precipitation is basically consistent.The change of observation environment is obvious from 2006 to 2010.Before moved the station in 2011,the temperature began to rise about 0.5 ℃ for 5 years since 2006 and the relative humidity decreased by about 4% for 10 years since 2000.The wind began to reduce about 0.6m/s for 5 years since 2006.There are some effects of detection environment change on historical data after moving the station such as the average temperature is lower than the original,the average wind speed increased,precipitation decreased,relative humidity increased and the correction must be done before using the data.According to contrast and analyze the observation data,it shows that the temperature of the station between the new and old site exist obviously negative difference,especially the lowest temperature.To know the influence of changing detection environment to meteorological elements sequence,it still needs to verify by a longer period data in the new site.
