Soil Carbon Dioxide Emission along a Permafrost Hillslope in Larix gmelinii Forest in China
Abstract Quantification of regional soil carbon changes in boreal forests in China is difficult for high spatial heterogeneity, especially considering soil CH4 fluxes in permafrost regions. This study attempted to quantify the variation of soil CO2 emission and its relationship with other soil prope...
