摘要
应用三维动力学模型ELcirc及粒子轨迹跟踪模型模拟2007年9～10月三峡库区支流香溪河的水流及水藻颗粒的输移.结果表明：长江干流水体倒灌入香溪库湾产生的回流使藻类颗粒向上游运动造成了水华爆发.此三维粒子轨迹跟踪模型可以较好地模拟水华过程,所得结论可供相关研究人员参考.
A 3-D dynamic model-ELcirc and a particle tracking model are applied to simulate the water flow and the movement of alga-particles in Xiangxihe River-a tributary of the Three Gorges Reservoir.The result shows that the backflow from the main stream of the Yangtze River into Xiangxi River makes the alga-particles move towards the upstream and then causes the algalblooms.This 3-D particle tracking model can simulate the process of the algal-blooms preferably,while the conclusion from it can provide some references for the relevant researchers concerned.
