Analysis of Precipitation Characteristics and Defensive Measures in Zedang Area

文章选取泽当气象台站1981年-2020年逐月降水数据,利用一元线性回归法和3年滑动平均法对泽当地区降水特征进行分析。结果表明,1981年-2020年,泽当地区降水量整体呈现增加趋势,降水量的气候变化倾向率为18.204 mm/10 a,增加趋势较为显著;除秋季,泽当地区其余3季降水量均呈现增加趋势,同年降水量增加趋势保持一致,尤以春季和夏季降水量对年降水量的贡献最大。

Based on the monthly precipitation data of Zedang meteorological station from 1981 to 2020,this paper analyzes the precipitation characteristics of Zedang area by using the single variable linear regression method and three-year moving average method.The results show that from 1981 to 2020,the precipitation in Zedang area shows an increasing trend,and the climate change tendency rate of precipitation is 18.204 mm/10 a,with a significant increasing trend,except in autumn,the precipitation in the other three seasons showed an increasing trend,which was consistent with that in the same year,especially in spring and summer,the annual precipitation in Zedang area has a significant seasonal variation.
