With 72 samples of soil which were taken in the vicinity of Syowa Station, Antarctica, carbon dioxide evolution rate, i. e. soil respiration, water content and nitrogen content were measured. The range of soil respiration rates at 10℃ was 0.0 to 84.9 mg C/(kg dry soil・day). Some of soil respiration rates measured at 10℃ were higher than those taken under the same condition with a few types of floral zone in Japan. Nitrogen contents in sample soil were very low with the range of 0.011 to 4.51 mg N/g dry soil. There were good correlations between soil respiration rates and nitrogen contents or water contents.
