摘　　要：为明确河道水污染防治效果,及时进行方向调整,提出了一种城市景观生态河道水污染防治效果评价方法。以溶解氧、总磷、总氮、氨氮、高锰酸盐指数为评价河道水质的单因子指标,并考虑到单因子指数和背景值差异较大、难以横向对比问题,参考《地下水质量标准》Ⅲ类标准值,构建综合评价函数和评价等级,得到监测河道的水质功能值和污染程度。经过实验分析得出,所提方法能够精准量化防治效果,为阶段性污染治理工作提供决策依据,具有极佳的应用价值。In order to clarify the prevention and control effect of river water pollution and make adjustments accordingly,an evaluation method of urban landscape ecological river water pollution prevention and control effect was proposed.This study takes dissolved oxygen,total phosphorus,total nitrogen,ammonia nitrogen and permanganate index as the single factor indexes to evaluate river water quality,and considering the large difference between the single factor index and the background value and the difficulty of horizontal comparison.The comprehensive evaluation function and evaluation grade are constructed with reference to the class III standard value of the groundwater quality standard.The water quality function value and pollution degree of the monitored river are obtained.Through experimental analysis,the proposed method can accurately quantify the prevention and control effect,providing decision-making basis for phased pollution control,and have excellent application value.
