伊春河流域土壤与沉积物中水溶性有机物的含量与吸着系数

Contents and sorption coefficients of soluble organic compounds in soils and sediment from Yichun River catchment

利用改变水土比的动态方法测定了采自伊春河流域土壤和沉积样品中水溶性有机物的含量与吸着系数；比较了不同样品间的差异及影响水溶性有机物含量和吸着系数的因素。研究结果表明，草甸沼泽土中水溶性有机物含量最高，沉积物中含量最低。水溶性有机物的吸着系数也呈同样的递变趋势。

Contents and sorption coefficients of sediment and soil samples from Yichun River catchment were measured using a Multiple Solid-Water Ratio Procedure. The difference in the measured results for various samples and the factors controlling these parameters were discussed.The highest content of soluble organic compounds was detected in soil sample collected from riverside wetland and the content of bottom sediment is the lowest among all samples studied. A similar trend of variation in sorption coefficients was observed.
