摘要
报道了杭州西湖截污和引灌钱塘江水后的一个富营养化模型。它按照年度描述西湖生态系统中的磷循环。状态变量有浮游植物磷、正磷酸盐、碎屑磷和沉积物磷。模型校准和检验结果表明,对于系统给定的强制函数(引水量和水温等)的改变,模型作出的状态变量的描述是合理的。并且利用该模型模拟在不同引水量及挖泥量下西湖水质变化。模型对引水及挖泥的效益所作出的评估可供综合治理时参考。
Focuses the researches on a eutrophication model after drainage of waste water and drawing water from the Qiantang River to the West Lake,the state variables in the model are phosphorus in algae cells,orthophosphate,phosphorus in detritus and phosphorus in sediment.The model describes phosphorus circulation in the ecosystem of the West Lake.The results of model calibration and verification show that the model can reasonably respond to the changes of forcing functions for drawing quantity and temperature of water.The model has been used to make the forecasts of water quality in the different drawing quantity.The predictions given by the model are also believed to the useful to comprehensively harness the West Lake.
