汾河水库及其上游干流水质趋势研究

Trend of Water Quality in Fenhe Reservoir and Upstream of the Fenhe River

本文以美国统计学家肯德尔提出的水质季节性肯德尔趋势分析方法为基础,结合山西省季节性河流的特点,改变了目前只进行了单一污染物浓度趋势分析的方法,采用7个函数的流量校正污染浓度的趋势分析方法,水质水量相结合对汾河水库及其上游干流河道的水质进行了综合趋势分析,指出了河流水质的变化趋势及引起变化的原因。

Based on the seasonal Kendall test,one kind of trend analysis method,com bined with the characteristics of the seasonal rivers in Shanxi Provin ce,the current trend analysis method in which only a pollution concentra tion is changed,the water quality trend in t he Fenhe Reservoir and upstream of th e Fenhe River is comprehensively analyzed by using seven pollution concentration functions,combining the water q uality and water quantity.The trend of the water quality variation and its causes are pointed out .
