Growing and winter mean CO_2 effluxes for the period 2006–2010 were 261 ± 124 (Coefficients of Variation: 48%) and 71 ± 42 (CV: 59%) gCO_2/m^2, respectively. This indicates that winter CO_2 efflux contributed 24% of the annual CO_2 efflux over the period of measurement. In tundra and boreal biomes, tussock is an important source of carbon efflux to the atmosphere, and contributes 3.4 times more than other vegetation types. To ensure that representativeness of soil CO_2 efflux was determined, 36 sample points were used at each site during the growing season, so that the experimental mean fell within ±20% of the full sample mean at 80% and 90% confidence levels. We found that soil CO_2 efflux was directly proportional to the seasonal mean soil temperature, but inversely proportional to the seasonal mean soil moisture level, rather than to the elevation-corrected July air temperature. This suggests that the seasonal mean soil temperature is the dominant control on the latitudinal distribution of soil CO_2 efflux in the high-latitude ecosystems of Alaska.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"　アラスカのツンドラと寒帯森林生態系(65.5°N から

gCO_2/m^2であった。これは、冬季の土壌二酸化炭素フラックスは、年間放出量の24％に相当するのが分かった。ツンドラと寒帯森林でのタソックは、炭素放出の重要なソースであり、他の植物より3.4倍高い。研究サイトの 観測点で測定した土壌二酸化炭素フラックスの代表性を算定するために、植物成長期間の間、サイトあたり36観測点は、80と90％信頼性下で全体試料の平均値の±20％以内で観測値の平均が当てはまる。土壌二酸化炭素フラックスは、7月高度を補正した気温より、季節平均土壌温度で比例し、土壌水分では反比例するのが、分かった。従って、季節平均土壌温度は、アラスカ高緯度生態系においての土壌二酸化炭素フラックスの緯度勾配を決定する重要な因子であるのが分かった。
