| 摘 要： | 本文以生态系统动力学模型CAEDYM为建模框架,紧密结合太湖生态系统结构与功能特点,以河道流量及其物质含量、风场、太阳辐射等为外部函数,以藻类生消及其相关营养盐变化过程为建模核心,建立考虑内源释放的各种形态氮、磷输移与转化的太湖整体三维藻类动力学模型。在选取关键性评估指标的基础上,构建非调水及实况调水两种情景方案,应用模型计算了两种情景方案下贡湖湾环境指标的时空变化,重点对比分析了蓝藻生物量的变化规律及其影响因素,较客观评估了引江调水对贡湖湾的水环境效应,阐明了引江调水对贡湖湾水环境的改善机制。

| Abstract: | An integrated algae dynamic model was developed for transport and transformation of all kinds of nitrogen and phosphorous released by the sediment in Taihu lake on a framework of large-scale ecosystem dynamic model called CAEDYM.This model,in consideration of the structures and functions of the lake's ecosystem,has a kernel function of modeling algae generation and vanishing,with external functions of river flow,river load content,wind field,solar radiation,etc.After selecting the essential evaluation index... |
