摘要：毛乌素沙地是我国沙漠化治理成功的经典案例，分析其以往的气候变化特点，有助于未来
更好地进行荒漠化防治与预警。本文以位于毛乌素沙地北缘的乌审召镇为例，利用1961-2020
年气象监测数据，通过增广迪基-福勒平稳性检验、曼－肯德尔趋势检验与趋势突变检验、累计
距平分析等方法，分析了气温、降水、大风和沙尘暴变化规律。结果表明：乌审召镇年平均气温

在波动中呈缓慢上升趋势，气温突变发生在1990年左右；降水量在1980-1981年间发生了由多

到少的突变，在2011年左右发生了由少到多的突变；大风和沙尘暴天气发生的天数在波动中呈
缓慢下降趋势，沙尘暴天气日数经历了上升—下降的过程，1990年之后沙尘暴日数趋势由20世

纪后期的波动下降变成21世纪初期的急剧下降。上述气象状况的变化在一定程度上了反应了
毛乌素沙地植被恢复的生态效应，整体改善。

Abstract:Mu Us Sandy Land is a classic case of successful desertification control in China! Analyzing the char⁃
acteristics of climate change in the past is beneficial to better prevention and early warning of desertification in the fu⁃
ture. Taking Wushenzhao Town, located in the northern margin of Mu Us Sandy Land, as an example, using meteoro⁃
logical monitoring data from 1961 to 2020, we analyzed the variation of temperature, precipitation, gale and sandstorm
by means of augmented Dicky-Fowler stationary test, Mann-Kendall trend test and trend mutation test, and cumula⁃
tive anomaly analysis. The results showed that the annual average temperature in Wushenzhao Town showed a slow
