Abstract: The paper aims to study the homogeneity of historical meteorological data and climate change tendency at Wutaishan. According to the temperature and precipitation data of Wutaishan Station from 1957 to 2013, homogeneity of historical meteorological data and climate change tendency at Wutaishan was analyzed by using the running T test, one- variate regression method, linear trend analysis and smoothing averages method. The results showed that: the relocation of Wutaishan Station caused significant difference on some meteorological data, but not on the precipitation data from May to October and January. The observed temperature was 4.6℃ higher than that before 1998 and the observed precipitation was 12.5 mm lower than that before 1998, which were caused by the station relocation. The annual average temperature and seasonal temperature were going up, and the rate of temperature rising was 0.32℃/10 a (annual), 0.36℃/10 a (spring), 0.18℃/10 a (summer), 0.31℃/10 a (autumn), 0.50℃/10 a (winter). The annual average precipitation and seasonal precipitation were going down, and the rate of precipitation drop was - 36.8 mm/10 a (annual), -7.9 mm/10 a (spring), -37.3 mm/10 a (summer), -11.4 mm/10 a (autumn) and -3.8 mm/10 a (winter).
