Abstract
This paper uses conventional ground observation data from 1992 to 2021,and uses univariate linear regression trend analysis,significance test,climate change test,and statistical methods to study the changing characteristics of climate resources in Alxa League.The results indicate that wind resources are decreasing year by year,while the average annual sunshine hours of light resources are gradually decreasing over time.The evaluation level of solar energy resources in Ejina Banner is B level or above;the trend of thermal resources is increasing year by year,with climate trends of annual average temperature,annual average accumulated temperature,and annual average frost free days being 0.4℃/10 a,82.2℃/10 a,and 3 d/10 a,respectively;the overall trend of precipitation resources is increasing year by year in time,gradually increasing from the northwest to the east and southwest in space.The annual average temperature experienced a sudden change in 2013.关键词
