中文摘要: 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 Ning
xia, the
homogeneity test was studied for annual mean temperature time series with the Po
tter
method. The results showed that among the 24 series, the 9 series were inhomoge
neous, and the other 15 series
were homogeneous. The discontinuous points were mainly found in the years 2001-2
006 an
d altogether had 7 discontinuous points (77.8%), in which 6 inhomogeneous series
were caused by r
elocated stations. Stations were relocated frequently in the 1950s, but the ti
m
es of relocated station were not the main causation of inhomogeneous series, a
nd the environment changes of relocated station were the main factors. Moreover,
the environment townish change of a station was also one of the factors, even
though the station does not move.
