Abstract：The article is based on daily precipitation observation data from 11 basic meteorological observation stations in Dezhou City from 1990 to 2020,The linear trend estimation method and the sliding average method are used to analyze the characteristics of precipitation climate change in the city.The results indicate that from 1990 to 2020,the sliding average precipitation in the early warm season of Dezhou City was 1.98 mm,and the sliding average precipitation in the middle warm season was 4.91 mm.Both the early and middle warm seasons showed an overall increasing trend,which passed the significance level test at a＝0.01.The sliding average precipitation in the late warm season was 1.42 mm,showing an overall decreasing trend,which did not pass the significance level test at a＝0.01.
