中文摘要	利用宁夏24个气象站的地面气温、总云量和低云量观测资料，分析了它们的年际及年代际演变趋势及相关关系。结果表明：近40年宁夏年平均气温波动升高，尤其是1990年以后；中部干旱带气温的年际变化较大，固原半干旱区气温变化幅度明显低于其它区域；1951年以来宁夏年平均总云量呈逐渐减少趋势，低云量下降趋势较总云量更为明显，2000年以后宁夏总云量有所增加。相关分析表明；宁夏年平均气温与年均总云量及低云量呈明显的负相关，均通过了0．01显著性水平检验，且低云量的相关更为显著；总云量和低云量与降水量呈显著正相关；同时，不同区域和不同季节总云量和低云量与气温、降水量的相关系数有明显差异。
英文摘要	The interannual and interdcadal changes and their correlation relations of air temperature, total- and low-cloud covers have been analysed, utilizing the observed data of the surface air tempernture and 24 stations over Ningxia in recent 40 years. The results show that the mean temperature increase in wavy way in Ningxia in recent 40 years, especially after 1990＇s on wards. The interannual changes of air temperature in arid region of middle Ningxia is largerl in Guyuan region, lesser. Since 1951, the annual mean tatal cloud cover in Ningxia gradully decrease, the decreasing tendency of low cloud cover is more obvious than that of the total cloud cover, but the cloud cover in Ningxia has increased after 2000. The correlation analysis indicates that there is a negative relation between annual mean air temperature and total and low cloud covers in Ningxia and they have passed the test of the significant level at 0.01 and the low cloud cover has a more significant relation with the temperature. There is a obvious positive relation between precipitation and total and low cloud cover. Meanwhile, the relation coefficents between the total and low cloud cover in different regions and seasons of Ningxia and the air temperature and precipitation have obvious differences.
