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.}, pages = {31--39}, title = {南極,昭和基地周辺の土壌呼吸 : 1.土壌呼吸速度と土壌の含水率,チッソ含有率との関係}, volume = {70}, year = {1980}, yomi = {イノ, ヨシオ and オオシマ, ヤスユキ and カンダ, ヒロシ and マツダ, タツロウ} }
