WASP水质模型在河流富营养化问题中的应用

摘要

生态系统动力学模型可以真实地刻画河流富营养化问题.基于这一模型,运用WASP水质模型对浑河支流细河2007年污染质运移问题进行数值模拟,并对模拟的效果进行分析与解释.结果显示,7月份在靠近工业园区和居民区附近河段,BOD浓度>140 mg·L<'-1>,污染严重,其主要原因为工业废水和居民污水的大量排放,表明基于生态系统动力学模型的WASP较以往的经验回归等统计模型更能反映河流富营养化问题的动态变化规律.%Ecosystem dynamics model can truly describe the river eutrophication problem. Based on this model, the authors study the numerical simulation of pollutant migration of Xihe in 2007 by WASP water quaulity model, and analyze and explain the simulation results. The results display that the concentration of BOD is more than 140 mg · L-1 in July near the industrial and residential areas, the main reason is a large amount emission of industrial and residential wastewater, which shows that WASP based on ecosystem dynamics model is more able to reflect the dymatic change law of river eutrophication than traditional experience regression model.
