河湖水生态系统数值模拟
构建多尺度耦合的水动力-水质-生态模型体系，形成「模型-观测-智能」闭环的数字孪生系统。
面向复杂工程水域与调度场景，构建多尺度耦合的水动力-水质-生态模型体系（1D/2D/3D），以 CE-QUAL-W2、Delft3D、EFDC 等为平台，刻画分层/异重流、营养盐循环、浮游植物群落竞争与沉积-再悬浮等关键过程；融合长系列监测、围隔实验与 UAV/卫星遥感数据，通过数据同化（EnKF/4D-Var）降低不确定性；提出基于 Zeu/Zmix 阈值的水华风险判识与情景模拟，并以多目标优化支持生态水文调度。主要任务包括藻类水华预测预报、河湖水生态系统过程研究与流域水资源优化管理。
