摘要
采用季节性Kendall检验法,利用近20a的水质数据系列,对滨州市17座引黄平原水库的水质演变趋势及其原因进行分析.结果表明,水库水质污染呈显著减轻趋势、水质咸化呈显著减轻或稳定趋势、营养盐浓度稳定且持续处于较高水平,演变原因主要是水源黄河水水质改善、咸化控制措施有效、外源转内源的持续长期影响,同时也存在发生富营养化进而影响供水水质安全的风险,需有效控制内源污染.
Abstract
The water quality evolution trend and reasons of 17 Yellow River Diversion Plain reservoirs in Binzhou City are analyzed,using the seasonal Kendall test method and the water quality data series of the past 20 years.The results indicate that the pollution of reservoir water quality shows a significant reduction trend,the salinization of water quality shows a significant reduction or stable trend,and the concentration of nutrients is stable and continuously at a high level.The main reasons for the evolution are the improvement of the water quality of the Yellow River,effective measures for controlling salinization,and the sustained long-term impact of external to internal sources.There is a risk of eutrophication affecting the safety of water supply quality,and effective control of internal pollution is necessary.
