摘　　要：应用和田市国家基准气象站1961-2009年逐月太阳总辐射资料,采用线性倾向估计、Morlet连续小波、滑动t检验法分析了49a来和田市太阳总辐射的趋势变化、周期及突变特征,结果表明:年太阳总辐射呈显著的减少趋势,减少率达96.8MJ/m2.10a,夏、秋、冬三季亦呈显著减少变化趋势;60年代平均辐射最多且明显偏多、80年代最少且明显偏少,辐射峰值出现在1970年、谷点在2004年,一年中夏季辐射最强、冬季最弱,6月最大、12月最小;表现出贯穿始终且逐年代增加的准22～27a、1988年以前较稳定的准6a两个明显周期,显著突变点在1976年减少、1987年增加。Using mensal sun general radiation data of national benchmark weather station in Hetian,adopting linearity incline estimate,Morlet series little wave,slide t test method to analyze the trend change,period and mutation of sun general radiation in Hetian during 49a,result showed annual sun general radiation was decreasing distinctly,decrease rate was 96.8MJ/m2·10a,sun general radiations in summer,autumn and winter were also decreasing;Average radiation was the most and increasing in 1960 decade distinctly.Average radiation was the lackest in 1980＇s and decreasing distinctly,radiation peak value was in 1970,radiation low value was in 2004,radiation was the strongest in summer and the least in winter in a year,June was the most and December was the least;show two distinct cycle of norm 22-27a a decade all the time and steady norm 6a before 1988,marked mutation was decreasing in 1976 and increasing in 1987.
