松花江同江断面高锰酸盐指数通量估算与分析

Estimation and Analysis of Pollutant Fluxes for the Songhua River Tongjiang Section

结合松花江同江断面2001-2005年流量和高锰酸盐指数监测数据,选用适当的数学模型对高锰酸盐指数通量进行估算。结果显示,高锰酸盐指数通量与流量变化趋势大体相同,8月份左右达到峰值。同江断面高锰酸盐指数通量与流量呈显著正相关,因此可用同江断面流量及建立的回归方程估计和预测汛期的高锰酸盐指数通量,节省工作量,为同江断面污染物通量估算提供理论基础。

Linked with the data of 2000 -2005 year flow capacity and the permanganate index in the Songhua River Tongjiang section, selected the suitable mathematic model to calculate the fluxes of permanganate index. The computed result demonstrated that it is more or less the same between the month flux of permanganate index and the month current capacity change tendency, achieved the peak value about August. In the Tongjiang section of Songhua River, The permanganate index flux and flow capacity had observably positive relations, therefore we can use Tongjiang section flow capacity and the regression equations to estimate and forecast permanganate index fluxes in the flood season, it saves the workload, in the same time, provide the rationale for the estimation of pollutant fluxes in the Tongjiang section.
