摘　　要：为掌握秦皇岛桃林口水库未来水质变化的状况,本文选取总磷(TP)、硝酸盐氮(NO3-N)、氨氮(NH3-N)、高锰酸盐指数(CODMn)和溶解氧(DO)等5项水质指标,基于2014~2015年水源站和出库站两个监测站的5项水质指标的监测数据,确定WASP模型的参数;再根据水源站2016、2017年5项水质指标来预测出库站的水质情况。研究结果表明:该WASP模型对5项水质指标的模拟值的判定系数R2均大于0.7,相关系数r均大于0.83;各项水质指标的实测值与模拟值的相对误差一般低于10%。WASP模拟效果良好,可以运用到桃林口水库的预测预警系统中和水库水质预测与管理的工作中,同时为秦皇岛市青龙县水环境保护与管理工作提供决策性参考与依据。In order to grasp the future water quality changes of Taolinkou Reservoir in Qinhuangdao, the total phosphorus(TP), nitrate nitrogen(NO3-N), ammonia nitrogen(NH3-N), permanganate index(CODMn) and dissolved oxygen(DO) were selected. Based on these five water quality monitoring data in 2014-2015 at the water source and the outbound stations, the parameters of WASP model were determined and then used to predict water quality of Taolinkou Reservoir in 2016 and 2017. The results show that the R2 of the simulated values of the five water quality indicators of the WASP model is greater than 0.7, and the correlation coefficient is greater than 0.83;the relative error between the measured values and the simulated values of the water quality indicators is generally less than 10%. It is shown that the established WASP can simulate water quality well and apply to the prediction and early warning system of Taolinkou Reservoir. At the same time, it provides decision-making reference and basis for Qinhuangdao water environmental protection and management work.
