Analysis of Spatiotemporal Changes of Land Surface Temperature in Shanxi for Carbon Peaking and Carbon Neutrality Goals
[Purposes]This paper aims to explore the variation rule of land surface temperature in Shanxi Province during the past 40 years,and provide reference for geothermal development and carbon peak path selection in Shanxi Province.[Methods]This paper selected the land surface temperature data of 108 stations in Shanxi from 1981 to 2020,used the methods of climate propensity rate analysis,M～K mutation detection,wavelet analysis etc analyze land surface temperature.[Findings]The land surface temperature of nearly 40 a in Shanxi showed a significant upward trend,with an increase rate of 0.499℃/10 a.The land surface temperature high in the south and low in the north,high latitudes are clearly lower than those in low latitudes,high altitudes are significantly lower than low altitudes.The trend of the Lüliang Mountain has a significant impact on the rise and fall of land surface temperature.The northwest has the fastest rate of warming.[Conclusions]The high value area of correlation coefficient of land surface temperature and time in the whole province basically coincides with the high value area of trend coefficient.The phase change of the land surface temperature is dominant,the high or low change tends to be consistent as a whole,and tends to be a more obvious warming trend after 1999.there are periodic oscillations of about 18 a,12 a and 6 a,and the land surface temperature in Shanxi has a tendency to be higher in summer and lower in au-tumn in the future.The land surface temperature variation is closely related to air temperature variation.About 2/3 of the stations showed negative correlation between land surface temperature and precipitation.About 1/3 of the sites have significant correlation between land surface temperature and sunshine duration.
