摘要
以漕河大册营至西庄段河流为研究对象,运用一维稳态水质模型对河流水质进行了分析和预测。通过Excl 对模型参数采用单一参数估算法完成估算并进行模型参数的确定阳验证。所建水质模型得出的计算值与实际河流的实测值相比,二者的相关系数达到高度相关。说明此预测模型具有较高的精度,可运用到实际中。模型预测结果及漕河河流自净化分析的结果表明漕河河水流往下游时,有机物的污染趋于减缓,对自洋淀的水质未造成严重影响;总汞及氮可能对沿岸地下水和白洋淀水质有一定影响,应控制水质的恶化程度。
A one-dimension model is chosen to predict the water quality and the model parameters are given and determined. By comparing the actual data with the predictor, the result of mode shows that both of them have high correlativity with the correlative coefficient reaching 0. 79. The forecast model has better precision and can be applied practically. The results of predicting model and Cache River＇s self-purifying analysis found that when Cache water flows downwards, the polluting tendency of organic molecular compound declines, which doesn＇t have had effect on the water quality of Baiyangdian.
