水质水量相关法在非点源污染负荷估算中的应用

降雨径流是形成非点源污染的主要影响因素，据此，根据监测资料建立了水质水量相关关系，将年径流量分割为地表径流与枯季径流，并将水质不量相关关系应用于地表径流，从而提出了有限资料条件下估算降雨径流污染年负荷量的水质水量相关法。应用实例表明，这种方法是可行的。

Correlation Method of Water Quality and Quantity and Its Application to Load Estimation of Nonpoint Source Pollution

Rainfall runoff is the main factor affecting the formation of nonpoint pollution. For this reason, the correlation relationship of water quality and quantity is established in accordance with the monitoring and measuring data. The yearly runoff is divided into the surface runoff and the runoff in the dry season, and also, the correlation relationship of water quality and quantity is used for the surface runoff, whereby presenting the correlation method of water quality and quantity to estimate the yearly load of rainfall runoff pollution in the case of limited data. The practical examples used in the studies indicate that this method is feasible and practical.
