摘要
Matlab具有强大的数值运算与处理能力,在许多领域都得到了广泛应用。在建设项目的地表水环境影响预测评价工作中,排污口下游河段污染物的浓度分布是重点关注的问题。采用现有的水质模型可以方便地计算出下游河段某点污染物的浓度,但不便于绘制浓度分布图。基于Matlab,采用随机数生成函数,通过编程,可以很方便地计算排污口下游河段任一点的浓度,并在此基础上生成浓度等值线图,从而为建设项目污染物排放对下游河段水环境质量的影响预测提供了重要依据。
MATLAB has been widely used in many fields for its powerful numerical calculation and processing capacity. Concentration distribution of pollutants in downstream from sewage outfall is a focus in the impact prediction and evaluation of construction projects on surface water quality. It is easy to calculate pollutants concentrations of a downstream point with the existing water quality model,but it is not convenient to draw the concentration distribution chart. MATLAB can be used conveniently to calculate pollutant concentration of a downstream point and draw concentration distribution chart with the randomly generated function and programming,which would provide important basis for the prediction and evaluation of construction projects impact on downstream water quality.
