河流污染物通量估算方法分析(Ⅱ)——时空平均离散通量误差判断

Analysis of the Estimation Methods for the River Pollutant Fluxes(Ⅱ) : Error Judgment of Time-Averaged or Section-Averaged Dispersion Fluxes

提出了一个简单的通量误差判断公式 ,对于采用以时空平均的一维对流量方式估算河流通量 ,提出了限制的条件 ,即排除不可靠的通量估值的方法 。

According to a simple formula of error judgment,a restrictive condition,which could be used to exclude the unreliable estimation method of fluxes,is proposed.The result provides a method for the error estimation and error analysis,with which the error contributions of time-averaged or selection-averaged dispersion fluxes to the fluxes estimation are evaluated.
