Abstract
The study of soil CO2 emission has been widely investigated through artificial control of the environment in the laboratory and in situ measurements in Norway, Alaska, Canada and Greenland. Soil temperature is one of the most important environmental factors for soil CO2 emission. The objectives are to report the monitoring of soil temperature and soil CO2 emission. Soil temperature for three points, 0.15, 0.55 and 1.08 m ranged from -14 to 11, -15 to 6 and -10 to 3, re-spectively. Period of the lowest temperature was from February to early April and highest temperature was from mid July to early August. Spatially averaged Soil CO2 emission for 16 sampling loca-tions ranged from 0.3 to 0.7 
mol m-2 s-1 and means of that were 0.56(
0.07) 
mol m-2 s-1 (2007), 0.54(
0.13) 
mol m-2 s-1 (2008), 0.51(
0.09) and 0.51(
0.09) 
mol m-2 s-1 (2009) during July of each year. Spatially averaged soil temperature ranged from 6 to 12 
C and soil water content ranged from 13 to 27% during measuring of soil CO2 emission. The patterns of soil CO2 emission for study periods generally followed those of soil temperature.
