摘要
为研究岳阳长江大保护水污染治理与水生态修复重点工程项目库在实施后的最终效果,文章建立了岳阳南北港河非稳态水环境数学模型。根据实测数据对参数进行率定后,以2014年作为水平年,对研究区域近期工程实施后的南北港河全年水质进行了模拟计算,并分析全年水质变化过程以及空间水质达标率。经过模型计算,入河污染削减后,整体上南北港河满足Ⅳ类水水质要求(TN除外),雨天水质略差于晴天。
In order to study the post-implementation final effect of the key project bank of water pollution control and water ecological restoration of the Yangtze River protection project in Yueyang City, this paper establishes the mathematical model for non-steady water environment of the South and North channels of South Lake in Yueyang City.After the parameters are calibrated according to the measurement data, we simulate and calculate the annual water quality of the South and North channels of Yueyang South Lake after the implementation of recent projects in the research area, with 2014 as the base year, and analyze the annual change process and the spatial compliance rate of the water quality in a whole year.Through the model calculation, the water quality of the South and North channels meets the requirements of Class IV water quality(except TN),while the water quality in rainy days is slightly worse than that in sunny days.
