| Abstract: | The experiment was carried in Sanjiang Plain in the northeast of China during the growing season in 2009.Soil organic carbon(SOC),as well as the soil active organic carbon fractions in the 0-20 cm soil layer of Calamagrostis angustifolia wetland under different water conditions were on monthly observation.Based on the research and indoor analysis,the seasonal dynamics of light fractions of soil organic carbon(LFOC) and microbial biomass carbon(MBC) were analyzed.The results indicated that the SOC contents h... |
