摘要
通过二维纵向横向平均水动力学和水质模型(CE-QUAL-W2模型)来模拟上海大型饮用水水库的水质状况。模型初步模拟了该水库中不同深度水层的水质状况,使用2011年1月到2011年11月单月(包含一年四季代表性)的数据对模型主要参数进行校正。结果显示,水质状况的模型计算值与实测值比较接近,与实际情况较吻合,AME和RMS值较好,预测该水库的水质是Ⅰ～Ⅱ类。通过本文对该(CE-QUAL-W2模型)的应用得出的结果显示,该模型也适合模拟一些具有湖泊特性的河流,尤其适用于对水体的水质评估。
The water quality in Shanghai drinking water reservoir is simulated by two-dimensional longitudinal and transverse average hydrodynamic water quality model（CE-QUAL-W2 model）.The model first simulated the water quality in different depths and the data of January,March,May,July,September and November in 2011（representing the four seasons）was adopted to calibrate the major parameters of the model.Results show that the values generated by the water quality model is close to the actual value and agrees with the actual situation.AME and RMS values are preferable,showing that water quality in the water isⅠ-Ⅱ.It is concluded that this model is also applicable to water quality simulation for rivers with lake characteristics,especially for the assessment of water bodies.
