摘要
以黄河干流重点河段水质变化趋势为例,采用季节性肯德尔检验方法,定量描述了河流水质变化趋势,分别分析了黄河干流兰州、潼关、花园口站的水质浓度变化趋势、污染物输送率变化趋势和流量校正污染物浓度变化趋势,并且探讨了水质管理的对策。
The article has adopted the seasonal Kendall parameter as the check model to respectively analyze water quality concentration variation trend,pollutants transmission rate variation trend and flow-calibrated pollu-tants concentration variation trend for the Yellow River trunk's Lanzhou,Tongguan and Huayuankou reaches.Finally the article proposes some measures for managing water quality.
