【摘要】 本文针对现行湖水总磷模型中的存在问题,探讨了均匀混合和非均匀混合两类湖泊总磷模型的建立方法。验算结果表明,不仅模型的计算精度能符合水质规划的要求,而且还较好地解决了大型浅水湖泊中总磷浓度分布的时空差异问题。更多还原

【Abstract】 This paper discusses some weakness in present water quality modelling of total phosphorus and puts forward a method of establishing models of total phosphorus according to uniformly mixed and noa-uniformly mixed lakes. The principle points are as follows:1. Establishment of equations of current field and concentration models.2. Solution of the equations.3. Parameter identification.4. Model verification.Some results observed in West Lake and Poyang Lake agree well with the calculated value, so mathematical models satisfied the requirment of water quality planning in lakes.更多还原
