摘要
本文利用江孜站1989-2018年的气温、降水量以及日照时数的气象资料,选用一元线性回归法对江孜县近30年气候变化特征进行分析。结果表明:近30年年平均气温呈变暖趋势,气候倾向率为0.39℃/10a;年降水量呈减少趋势,气候倾向率为-4.16mm/10a;年日照时数呈减少趋势,气候倾向率为-42.1h/10a。
Based on the meteorological data of temperature,precipitation and sunshine hours of Jiangzi station from 1989 to 2018,the univariate linear regression method is used to analyze the climate change characteristics of Jiangzi County in recent 30 years.The results show that:in recent 30 years,the average temperature shows a warming trend,and the climate tendency rate is 0.39℃/10A;the annual precipitation shows a decreasing trend,and the climate tendency rate is-4.16mm/10a;the annual sunshine hours show a decreasing trend,and the climate tendency rate is-42.1h/10a。
