Abstract: The study indicated that the semivariogram function of temperature in semi-aerobic landfilling structure could be well modeled by the linear with sill model. The correlation range of the profile was 3.5 m, and the sill value was 83.6. The unmeasured temperature values were interpolated with Kriging method, and the temperature isoline showed that high temperature region located at 3~5.5 m in the vertical direction of the middle part, while low temperature area laid in 0~1 m on the two sides of the landfill structure and substrate. The weighted average temperature of the profile was 59.80 ℃, which could be regarded as the indicator of landfilling structure’s formation.
