Solar radiation is the most basic and important energy source of the earth surface. It is very important to analyze the change of the solar radiation for regional climate and agricultural development. This study uses the meteorological data of 4 meteorological stations in the Ebinur Lake oasis area from 1961 to 2013 and the methods of the least squares discriminant analysis, anomaly analysis, MannKendall trend analysis and wavelet analysis to analyze the periodic change regularity of the solar radiation. The results show that: (1) The annual amount of radiation decreased with a relative change rate of 128; the fluctuation was relatively stable. The amount of radiation was mainly concentrated in the period from May to August, accounting for 52% of the year, which showed a normal distribution. A downward trend can be found in all months, with the decline rate being the largest in July. (2) The total amount of radiation in the Ebinur Lake oasis mainly concentrated in summer and autumn; the change trends of the four seasons were basically the same; there appeared the alternative process from lighting to dimming. Through the threshold test at the level of 99%, the amount of radiation showed a mutation in 1986 The change of annual total radiation was basically the same with changes of radiation in four seasons. (3) For the 21year, 10year, and 7year period cycles, there were relatively bright and dark periods, but the oscillation periods were different.
