摘要
依据近20a现场监测数据,结合净化试验,应用回归分析法建立了大沽河水体净化模型,研究了其常规流量下(污染较重)的水体自净规律,对确定大沽河水环境容量、污染物总量控制目标与水质保护目标,具有重要现实意义。回归分析法比较适用于北方季节性河流水体净化能力的研究,准确性较高,且具有较强的推广价值。
Based on monitoring data over the years and the self-purification experimentation, self- purification model of Dagu River was set up using recurrence analysis, the self-purifica- tion principle of Dagu River with routine flux （the pollution is serious） was studied, It has significant importance in determining the water environment capacity, the target of totality control of water pollutants and water quality level of Dagu River, it has also significant reference value in studying the other seasonal rivers in north China.
