【摘要】 为了模拟计算研究区长江沿岸污染带的污染负荷量,应用有限体积法及通量向量分裂方法(FVS)建立了考虑非点源影响的平面二维水环境数学模型;同时对水源地河床演变和岸线开发利用情况进行了分析.结果表明:研究区岸线污染负荷总量超标,水源地受岸源污染较重;水源地近期萎缩较快,河床处于淤积阶段.更多还原

【Abstract】 A 2D water environment numerical model,considering the non-point source pollution,was set up to simulate pollution loads along the Yangtze River in the studied area by use of the finite volume method and flux vector splitting(FVS) method,and the river bed evolution and river bank exploitation at the water source site were analyzed.The result shows that the total amount of pollutants along the bank is over-standard,the water source site is seriously polluted and shrinks fast,and the river bed is in the silting state.更多还原
