摘　　要：根据五道梁地区1980—2020年逐月降水气温资料,采用Mann-Kendall检验、小波分析等方法,分析近40年五道梁降水气温变化特征及其相关性。结果表明,1980—2020年,五道梁地区年平均气温和四季气温皆呈上升态势,四季平均气温按照季节交替有规律地发生变化,多年平均降水量为317.3 mm,年降水量呈显著增加趋势,降水量增大主要归因于暴雨量的增加。Based on the monthly precipitation and temperature data of Wudaoliang Area from 1980 to 2020,the study analyzes the variation characteristics and correlation of precipitation and temperature in Wudaoliang Area in recent 40 years through Mann-Kendall test and wavelet analysis.The results show that both the annual average temperature and the four seasons temperature in Wudaoliang Area show a rising trend from 1980 to 2020,and the four seasons average temperature changes regularly according to the seasonal alternations.The annual average precipitation is 317.3 mm,the annual precipitation shows a significant increasing trend,and the increase of precipitation is mainly due to the increase of heavy rainfall.
