摘　　要：利用2004—2007年内蒙古地区50个地面自动气象站与人工平行观测期间的数据,对自动与人工观测的气温、相对湿度、地表温度进行了差异分析,统计了两种观测之间的对比差值。对各要素观测差异在全区的分布特点进行了分析。结果表明:自动观测与人工观测各气象要素均存在一定的差异,但大部分地区各要素的差异都在自动站误差允许范围之内;造成差异的原因是多方面的,包括仪器本身存在缺陷及观测方法不一致等。Using the data of temperature, relative humidity, surface temperature of the recent 5 years （2004-2007） in Inner Mongolia from ground automatic weather stations and the manual parallel observation over the same period, analyzed the difference between the two kinds data, statistic the contrast differences between these two observations. Then the distribution characteristics of differences from the two observations for various factors in Inner Mongolia were analyzed. The results showed that the differences must exist between the two kind observations of meteorological factors. But the error of the various factors in the most districts is permitting in the scope for the automatic weather stations. There are many reasons, including apparatus itself flawed and inconsistent observation methods and so on.
