Abstract The article uses meteorological data from five meteorological stations in the Shiyang River Basin spanning from 1960 to 2019,and employing linear trend analysis,anomaly analysis,and moving average methods,we analyzed the spatiotemporal characteristics of climate change within the basin.The results indicate a significant increasing trend in temperature within the Shiyang River Basin,with a rate of 0.373 ℃ per decade.Precipitation exhibits a fluctuating upward trend,increasing by 7.8 mm/10 years,among with Tianzhu experiencing the fastest growth and Gulang the slowest.The number of annual strong wind days shows a gradual increase,rising by 0.015 days per decade,with Tianzhu and Yongchang experiencing an upward trend,while Gulang,Wuwei,and Minqin show a decreasing trend.Dust storms have significantly decreased,with a variation of -2.38 days per decade,particularly evident from the late 1980s to the late 1990s.
