水体富营养化综合水质模型及其应用研究

Study on Eutrophication Synthetic Water Quality Model and Its Application

针对水体富营养化问题,研讨了一种多参数水体富营养化的水质生态模型(WASP_4)。在阐述其原理和计算方法的基础上,结合汉江武汉段1992年发生水华事件的实例进行水质模拟。其特点是,不仅能够较好地模拟浮游植物的变化过程,而且能够提供发生水华问题的原因和生态机理的解释。

In allusion to the eutrophication problem of water body, discussion on a kind of ecological water quality model with many parameters WASP4 was presented. Based on expounding the principle and calculation method of the model, water quality simulation, combining with the example of eutrophication occurrence happening in River Hanjiang in 1992 has been conducted. The characteristics showed that the model not only simulated preferably the change process of phytoplankton, but also explained the cause of eutrophication occurrence and ecological mechanism.
