摘　　要：利用陕西省74个台站1961-2008年气温资料和台站沿革资料,采用二相回归法进行均一性检测和订正。结果发现台站迁移对气温资料的均一性有明显的影响,陕北台站迁移较少,关中和陕南迁站较多,全省74个台站中有24个台站资料的非均一性是因为台站迁移而引起的,对其中的12个台站进行了调整,使得全省气温序列从南至北分布具有较好的‘均一性'。Abstract： By the method of two-phase regression （TPR）, using temperature dataset and the information of the meteorological station＇s historical evolution from 1961 to 2008, the temperature series of 74 stations in Shaanxi Province were detected and adjusted. The results have shown that： station relocation has influence on the homogeneity of temperature series in Shaanxi Province; there are few station relocations in the northern Shaanxi and more in central and southern Shaanxi; the temperature series at 24 stations are apparently inhomoge- neous because of station relocation, and among them the temperature series at 12 ,stations are adjusted. This work makes the temperature series as homogeneous as possible over Shaanxi Province.
