摘要:
为了解长江黄石段水质状况,为该流域水环境治理和保护提供科学依据,运用水污染指数法和模糊综合评价法分析2014至2018年长江黄石段三峡断面和风波港断面的水质情况.研究结果表明,水污染指数法显示两个河流断面近五年水质类别均在Ⅴ类及以上,水质污染较为严重,其中2014年均为劣Ⅴ类水质.模糊综合评价法根据最大隶属度原则判断出2017年、2018年三峡断面和2017年风波港断面属于Ⅰ类水质,其余时期两个断面均为Ⅴ类水质.两种评价方法均表明总氮是影响河流断面的主要污染物.
This paper analysed the water pollution index and fuzzy comprehensive evaluation method to investigate the water quality of the Yangtze River in Three Gorges and Huangshi sections.The data between the years 2014 and 2018 of the Yangtze River is examined to provide a scientific basis for water quality treatment and protection of the Yangtze River basin.The results derived from the water pollution index method show that the water quality of the two river cross-sections in the past five years polluted seriously which is considered as Class V or above.Among them,the water quality in the year 2014 is found as most inferior as of Class V.According to the fuzzy evaluation principle,the water quality of Three Gorges section in between the years 2017 and 2018,and Fengbogang section in the year 2017 are found as of Class I,while the rest other periods are found as of Class V.Both evaluation methods show that total nitrogen is the main pollutant affecting the river cross-section.
