摘　　要：根据水域纳污能力计算规程,中小型河流纳污能力的计算推荐采用河流一维水质模型。由于基础观测资料普遍不足,模型的河流流速、污染物综合衰减系数2个重要参数的取值往往缺少可靠依据。以浙江省永康市水域纳污能力的计算为例,基于现有水文、水质观测成果,对河流流速和污染物综合衰减系数的取值方法和取值范围进行分析探讨。According to the calculation criteria of watershed environmental capacity,a one dimensional model isrecommended for most of medium or small rivers. The estimation of two important coefficients in the model,which areriver flow velocity and pollutant comprehensive degeneration coefficient,are basically unreliable due to the insufficientdata. Based on the field observation and the calculation of the river environmental capacity of Yongkang city,the methodto determine these two important coefficients in the model and the range of these two coefficients will be discussed andanalyzed in this study in order to construct a one dimensional model representing the river environmental capacity ofYongkang city.
