| 摘 要： | 选取宁夏24个气象站从建站到2006年年平均气温资料,采用Potter检验法对年气温资料进行均一性检验.结果表明:宁夏有9个测站年气温资料存在间断点,有15个测站无间断点;间断点主要集中在2001-2006年,共有7个,占总数的77.8%,其中有6个测站是因为站址迁移造成的;20世纪50年代测站的迁移最频繁,迁移次数不是造成年平均气温序列非均一性的直接原因,迁移前后测站环境的显著改变是主要因素,测站未迁移但测站环境城镇化变化也是因素之一.

| Abstract: | By the use of annual mean temperature data of 24 meteorological stations in Ningxia,the homogeneity test was studied for annual mean temperature time series with the Potter method.The results showed that among the 24 series,the 9 series were inhomogeneous,and the other 15 series were homogeneous.The discontinuous points were mainly found in the years 2001-2006 and altogether had 7 discontinuous points(77.8%),in which 6 inhomogeneous series were caused by relocated stations.Stations were relocated frequently... |
