摘要
以水溶性腐殖酸含量很高的伊春河为例,利用冬季冰封无外源输入的条件,在有关室内模拟研究的基础上,通过现场采样及测定,建立了伊春河河水水溶性腐殖酸的内源释放模型.根据同期采集样品进行的验证表明。
The autochthonous release of dissolved humic substances was modelled for Yichun River during winter when allochthonous inputs were totally cut off. The model was developed based on the results of laboratory simulation experiments using sediment samples from the same river. Data on concentrations of humic substances, river channel formation, sediment properties, and flow rate collected in the field were employed for parameter identification and model verification. The effect of flow velocity on the release kinetics was discussed as well.
