新疆主要河流水质变化趋势分析

Analysis on the Change Trends of Water Quality of Main Rivers in Xinjiang

水质资料序列的非正态分布、季节性、流量相关性、预测值、小于检出限的数值和序列相关性，造成了对水质时间序列分析研究的复杂化。本文应用季节性肯达尔非参数检验方法，对新疆各地区主要河流１９８６—１９９１年之间的水质变化趋势进行了系统的分析，对于宏观认识新疆河流水质变化有着重要意义。

This paper using the seasonal Kendall Non-reference Testing Method systimatically analysed the change trends of water quality of main rivers in Xinjiang betwelen 1986 -1991. It is of great importance for macroscopic understanding the water quality change of river in Xinjiang.
