摘要
水环境评价既存在模糊性又存在随机性,水库水环境评价方法的全面性和精确度有待提高。基于多因子环境质量指数和灰色系统理念,建立内梅罗灰色综合法,对铜山源水库水环境开展评价,结果表明:铜山源水库水环境状况总体良好,满足水库功能要求;2017—2020年,水环境质量略有好转,改进的内梅罗指数从1.32降低到1.17;庙前和白鹤岩入库口断面常年受工业和农业污染严重,总氮质量分数TN和总磷质量分数TP常年超标是造成铜山源水库水质问题的主要原因。最后,提出了铜山源水库水环境污染的防治措施。
Water environment assessment has both fuzziness and randomness.The comprehensiveness and accuracy of reservoir water environment assessment methods need to be improved.Based on the multi-factor environmental quality index and grey system concept,the Nemerow-Grey comprehensive method was established to evaluate the water quality of Tongshanyuan reservoir.The results showed that the water environment of Tongshanyuan reservoir was generally good and meet the requirements;from 2017 to 2020,water quality improved slightly,with the improved Nemerow index decreasing from 1.32 to 1.17;the inlet cross sections of Miaoqian and Baiheyan were heavily polluted by industry and agriculture,as well as TN and TP values exceed the standard all year round,which was the main cause of water quality problems.Finally,the prevention and control measures of water environment pollution in Tongshanyuan reservoir are proposed.
