感潮河网水环境容量影响因素研究

Study on Effect Factors of Water Environmental Capacity for Tidal River Network

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 。

The primary factors affecting water environmental capacity for tidal river network, such as tide, storage capacity, water conservancy project, pollutants decay coefficients and boundary water quality of drawing water,were studied in this paper.Based on the water quality model for tidal river network, the computational method of aquatic environmental capacity was improved. The time space changing law of the influence of above factors on aquatic environmental capacity was studied by the example of the river network of Punandong Area in Shanghai, and then the permitted pollutants discharge amount was put forward.
