摘要
针对大型水库水质要素分布呈现明显三维效应的特点,建立了一种考虑温度分层影响的DO,CODCr,TP,TN三维水质预测模型。采用二滩鱼感鱼河支库原型观测资料对模型进行验证,并分析了模型误差产生的原因及模型的适用性。分析结果表明,所建模型可以用于对DO,CODCr,TP,TN等水质要素的数值模拟,模拟成果可为大型水库修建的环境影响评价提供科学依据。将该模型应用于某在建大型水库,成功模拟预测了该水库水质要素的三维分布特性。
Based on the obvious three-dimensional characteristics of water quality distribution of large reservoirs, a three- dimensional water quality model for DO, CODcr, TP and ＇IN considering the effects of stratified temperature structure was established. The model was verified by use of the observed data of Ganyuhe Reservoir of Ertan Hydropower Station. The causes for error and the applicability of the model were analyzed. The results show that the proposed model can be employed to simulate the water quality elements of DO, CODcr, TP and TN in large reservoirs. It can provide scientific basis for environmental impact assessment of development of large reservoirs. A case study of a large reservoir indicates that the above model successfully predicts the three-dimensional distribution features of its water quality elements.
