摘　　要：采用SNHT、累加距平法、秩检验法,对辽宁省48个代表站1961～2008年的年平均气温序列进行了非均一性检验,并结合台站历史沿革资料对非均一性产生的原因进行了分析。结果表明,3种方法均能有效地对台站的非均一性做出检测,秩检验法和SNHT检验法有一定的互补性。气温非均一性产生的主要原因是台站迁移,并且非均一性断点主要集中在20世纪70年代。The homogeneity test of annual mean temperature series was carried out using mean temperature over Liaoning Province from 1961 to 2008 by means of SNHT,cumulative-departure and rank test.The reasons of inhomogeneity were analyzed with the metadata information of 48 weather stations.The results showed that all of the three methods were valid for inhomogeneity tests of temperature sequences,and rank test had certain complementary with SNHT test.Station relocation was the significant reason for inhomogeneity,which mainly occurred in 1970 s.
