The satellite thermal infrared remote sensing is getting more and more attention in earthquake science, for satellite remote sensing has a significant advantage of the space information. Meanwhile, there exist many key basic problems which should be solved, for instance, what data are suitable for the corresponding research. In this paper, the relationship between two kinds of land surface temperatures obtained by field measurement and satellite remote sensing is studied, based on data from March, 2006 to February, 2008. Our results indicate that: (1) as for the two kinds of land surface temperatures, the difference at night is smaller than that of day, and correlation at night is more significant than that of day; (2) No matter whether it is day or night, the correlation between long period components of the two kinds of land surface temperature is more significant than that between short period components. This means that there is essentially no difference between day and night when analyzing temperature component of long period. In summary, the relationship between the two kinds of land surface temperatures is obtained preliminarily, which is helpful to data selectiont.
