摘　　要：为得出应用于河湖水质评价和应急监测中的标准模型,本文基于RAGA-PPC模型对滆湖水质进行了评价,并对5种不同水质指标数值进行了模拟,结果表明:该模型按照投影追踪的原理,将水质等级分为了5个等级,滆湖3个区域核心区、缓冲区和开发控制利用区的水质分别属于Ⅱ级、Ⅲ级和Ⅱ级,结论与实测值基本一致,而基于该模型对水质指标进行模拟结果可知,模型模拟结果的误差较小,与实测值的一致性较高,表明模型模拟精度较高,验证了模型在水质评价与应急监测中的先进性和科学性。In order to obtain the standard model applied in river water quality assessment and emergency monitoring,the water quality of Gehu based on RAGA-PPC model was evaluated,and the values of five different water quality indicators were simulated.The results showed that the model was divided into five grades according to the principle of projection tracking.The water quality of the three regional core areas,buffer zones and development control utilization areas of Gehu belonged to Grade II,Grade III and Grade II respectively.The measured values were basically the same.The error of the model simulation results was small,and the consistency with the measured values was high.It indicated that the model had high simulation accuracy,which verified the advanced and scientific nature of the model in water quality assessment and emergency monitoring.
