Land surface temperature is a parameter that affects many natural and human processes. In this study, the spatial distribution of surface temperature in Zanjan province from 2001 to 2023 was investigated. In addition, the effects of elevation, longitude, and latitude on the temperature distribution of the land surface, its spatial pattern, and the temperature zones of the province were evaluated and revealed using partial correlation methods, G* statistic, and clustering analysis, respectively. The results showed that the mean temperature of the land surface is 24.6 C° during the day and 5.3 C° at night. The relationship between elevation, longitude, and latitude with surface temperature is negative. elevation has the greatest effect on temperature, but the effect of latitude and longitude is weak. However, the temperature decreases by moving from south to north, west to east, and from lowlands to high elevations. The land surface temperature in the province follows a cluster pattern with a certainty of 95% or more, in which the lowlands and heights of the province have played the most role in its formation; Also, the province can be divided into four temperature zones, where the direction and boundaries of the zones follow the shape of the land. The mean daytime land surface temperature of the earth in the first group is 23.9 C°, the second group is 27.3 C°, the third group is 28.8 C°, and the fourth group is 18.8 C°. In addition, the mean temperature at night in the first group was 4.4 C°, the second group was 6.9 C°, the third group was 12.1 C°, and the fourth group was 1.9 C°.
