One year comparative observational data were used in the paper from 13 new and old stations, which have been changed or are going to change since 2008. We respectively calculated the absolute difference, standard deviation of distance and the correlation coefficient between elevation difference and change distance for the new and old station. It showed that, there was a positive correlation between the absolute difference and standard deviation of difference of annual average temperature, maximum temperature, minimum temperature, relative humidity to distance and elevation difference for the new and old station, and a negative correlation between the year wind direction coincident rate to them. There was a significant impact of the site distance on maximum temperature, wind direction coincident rate, and both of the correlation coefficients passed significance level at α =0.05. While there was more significant impact of elevation difference on mean temperature, minimum temperature, relative humidity, and all the correlation coefficients passed significance level at α =0.05. The absolute differences of annual mean temperature, annual minimum temperature and annual relative humidity in the mountain area were more than twice in the majority plain region, and wind direction coincident rate was one order of magnitude smaller than that in the plain region. Due to the big difference of the surface environment, there was larger absolute differences and standard deviations in annual mean temperature, minimum temperature and relative humidity in the extremely arid Turpan area in eastern Xinjiang, while the wind direction coincident rate was smaller than the other stations.
