| 摘 要： | 基于新疆53个气象台站1960—2005年逐月降水资料,通过Mann-Kendall非参数趋势检验方法,对新疆近50 a来年降水量和12个月降水量的趋势进行了分析,并计算12个月对年降水量的贡献率,同时通过SequentialMann-Kendall方法分析了27个台站年降水量显著增加趋势发生的时间突变点。结果表明,新疆近50 a来年降水量显著增加,北疆和南疆趋势最为明显;其中冬半年(1、2、11月和12月)这4个月的降水量增加趋势显著,对新疆年降水量的贡献较大;新疆大部分台站年降水量趋势发生突变的时间点在20世纪80年代以后。 |

| Abstract: | The spatial-temporal variation of the annual and monthly precipitation and the abrupt change of the annual precipitation were analyzed with Mann-Kendall trend test and sequential Mann-Kendall test based on monthly precipitation data of 53 climatic stations from 1960 to 2005.The results indicated:(1) The precipitation significantly increased in recent 50 years,especially in Northern and Southern part of Xinjiang.(2) The precipitation increased remarkably in January,February,November and December,contributing... |
