外源碳添加对三江湿地土壤有机碳矿化的影响
Effects of Exogenous Carbon Additions on Soil Organic Carbon Mineralization in Sanjiang Plain Wetland
摘要
Abstract
A simulation experiment was conducted to investigate the effects of different concentrations of exogenous carbon addition on soil organic carbon(SOC)mineralization.The results showed that the cumulative SOC minerali-zation increased significantly with higher carbon addition concentrations,and the average mineralization rate peaked significantly at an addition concentration of 1.50％.The cumulative SOC mineralization was significantly positively correlated with microbial biomass carbon(MBC),and the exogenous carbon concentration explained 48.70％of the variation in mineralization.Exogenous carbon addition significantly promoted SOC mineralization in the wetlands of the Sanjiang Plain,with a threshold concentration of 1.50％.关键词
