摘　　要：针对广佛跨界河网区主要监测断面污染物通量的问题,本文主要从涨潮通量、退潮通量和净通量三个方面着手,选取主要污染控制因子氨氮、高锰酸盐指数和总磷作为污染物指标,通过对比各断面在涨退潮和两次测量期的污染物通量,以及开展断面之间的对比分析,探究河道水体水质变化的规律,为广佛水资源管理保护决策提供技术支撑。This paper addresses the issue of pollutant flux at key monitoring sections in the Guangzhou-Foshan cross-border river network area.It focuses on three aspects:tidal flux,ebb flux,and net flux.The main pollution control factors selected as pollutant indicators are ammonia nitrogen,permanganate index,and total phosphorus.By comparing the pollutant flux at various sections during tidal and ebb periods,as well as between two measurement periods,the study explores the patterns of water quality changes in the river.This analysis provides technical support for water resource management and protection decision-making in the Guangzhou-Foshan area.
