摘要
应用PHREEQC软件建立了基于水动力学作用的温岭市太湖水库藻类生长模型。选用2007年度温岭市太湖水库总磷、总氮、水温、叶绿素a的实测值,采用三次样条插值的方法估计出每一天的总磷、总氮、水温、叶绿素a的数值,对模型参数进行了率定和验证。将建立的模型应用于2009年温岭市桐岭水库水华暴发的模拟预测中,结果表明本文所建立的模型进行模拟运算精度较高,可以应用于中小型水库水华暴发的模拟预测方面。
An algae growth model, based on the influence of water flow velocities on algae growth, was developed in this study using PHREEQC software. The experimental data of total phosphorous, total nitrogen, water temperature and chlorophyll a in Wenling Taihu reservoir in 2007 were adopted. Estimated data of every day were obtained by interpolation method for the calibration and verification of the model parameters. The established model was applied in the simulation and prediction of the algae blooms in Wenling Tongling reservoir in 2009. It was demonstrated that the simulated results fitted well with the measured data, which indicated that the developed model could be used to predict the algae blooms in small and medium- sized reservoirs.
