摘　　要：利用SNHT和t检验方法对临河站1956—2008年逐年、季平均气温和地面温度序列进行均一化检验,结果表明:站址迁移和周围高大建筑是造成资料非均一性的主要原因。年平均温度的不连续点分别为1980、1995年,与站点迁移和高大建筑的建设时间吻合,表现在季节上为冬、夏季明显,春秋次之。The annual and seasonal average temperature and surface temperature sequence of Linhe meteorological Station,from 1956 to 2008 years,are tested by SNHT and t test methods,and the results showed that the transfer station and the surrounding tall buildings are the main reasons for the non-homogenization of the data.The discontinuous points of annual average temperature are the year of 1980 and 1995,which matched to the time of the transfer station and the construction of tall buildings.It is more obvious in winter and summer than in Spring and Autumn.
