中文摘要:
      水质指数(WQI)在环境保护的日常工作中发挥了重要作用。以鳌江为例,运用加拿大环境部长理事会水质指数(CCME WQI)方法,选取pH、溶解氧、高锰酸盐指数、氨氮、总氮、总磷、石油类、氟化物、阴离子表面活性剂、粪大肠菌群10项水质监测项目,评估了入海河流干流感潮河段4个监测断面的地表水环境质量,并对CCME WQI与最差因子法以及CCME WQI优缺点进行比较和分析。研究结果显示,2014年埭头、江屿、方岩渡、江口渡监测断面水质分别为良好、较差、中等、中等。与传统水质评价最差因子法比较,运用CCME WQI评价结果容忍度较高,更贴近实际水质状况。CCME WQI量化形式为属地流域环境管理带来便利。监测断面水质目标和参评项目对CCME WQI评价结果起决定性作用。针对CCME WQI在实际应用中存在的问题给出了建议。
英文摘要:
      Water quality index plays an important role in supervising water environment by department of environmental protection. Environment Water Qaulity Index (CCME WQI) method of Canadian Council of Ministers was used to evaluate water quality of four sampling sites of the Aojiang River tidal river, which select pH, DO, CODMn, NH3-N, TN, TP, petroleum, F-, LAS and fecal coliform as 10 water monitoring parameters. Advantages and drawbacks of CCME WQI were discussed comparing with single-fator-method. The results showed that water quality of Daitou, Jiangyu, Fangyandu and Jiangkoudu monitoring section in 2014 can be classified as good, inferior, medium and medium, respectively. The evalution results of CCME WQI were much closer to reality than single-factor-method and CCME WQI quantification also provided convenience for environmental management. Furthermore, water quality objectives and monitoring parameters played a crucial role in the CCME WQI calculation. Finally, suggestions of CCME WQI application in environment moitoring to water quality assement were offered.
