水环境容量一维计算中不均匀系数研究
Non-uniformity Factor in One-dimension Computation of Water Environmental Capacity
【摘要】 文章介绍传统地表水环境容量一维计算方法,针对其缺陷提出考虑不均匀系数的计算方法。介绍混合区概念及其允许范围,应用二维水质模型求解不均匀系数,并分析其计算结果。作为实例,对广西红水河某河段水环境容量进行计算,取得了很好的效果。
【Abstract】 Conventional method for computing one-dimension water environmental capacity was introduced,with non-uniformity factor taken into account.The concept of pollutant mixing zone and its allowable limit was presented,non-uniformity factor by using mathematic model of two-dimension water quality was used for computing water environmental capacity of Hongshui River,Guangxi Province and results turned out to be very effective.
