研究了感潮河网的水环境容量。研究表明影响感潮河网水环境容量的主要因素为 :潮汐作用、调蓄库容、水利工程的调控运行、污染物的降解系数和边界引水水质。基于感潮河网水质模型 ,完善了其水环境容量的计算方法。以上海市浦南东片河网为例 ,分析了感潮河网水环境容量在上述因素影响下的时空变化规律 ,并提出了相应条件下的污染物日允许排放量
The water environment capacity of tidal river network is studied. The results show that the main factors influencing water environment capacity of tidal river network are: tidal effect, storage capacity, regulation and control of water conservancy project, degradation coefficient of pollutants and water diversion at boundary. Based on the tidal river network water quality model, the calculation method of water environment capacity is improved. Taking Shanghai Pu’nan Dongpian river network as an example, the temporal and spatial variation of water environment capacity of tidal river network under the above factors was analyzed and the daily allowable emission of pollutants under the corresponding conditions
