肯达尔检验方法在干旱区河流水质趋势分析中的应用

Application of the Kendall Test Measure on Seasonal Stream Water Quality Trend Analysis on the Arid Region

季节性肯达尔流量检验是一种可以消除季节和流量影响的水质趋势分析的方法。本文介绍了该方法的基本原理,并运用该方法实际分析了白杨河水库的水质变化趋势。结果表明,该方法不仅能较好的反映出其水质变化趋势,同时还能够反映出其污染源的类型。

Seasonal Kendall flow test method can analyse the trend of water quality while it can dismay the season and the runoff influence. This paper introduces the basic principle of the method and analyses the water quality trend of Baiyanghe reservoir. The outcoming indicates that the measure can not only calculate the water quality trend but also can reflect the pollutant source type.
