摘　　要：监测流域水质的状况、分析水质变化的趋势有利于合理开发利用流域水资源,实现水资源的可持续发展。在玛纳斯河流域2005年水质监测资料的基础上,选择玛纳斯河、蘑菇湖水库、大泉沟水库及夹河子水库作为代表性站点,进行流域地表水水质的空间变化趋势分析,结果表明流域水质污染程度丰水期重于平水期和枯水期;另外,以2001-2005年4个代表性监测站点的水质数据为例,采用季节性肯德尔检验法对流域地表水水质时序变化趋势进行分析,结果显示:流域整体水质以稳定趋势为主,占整体变化趋势的45%;水质参数中,BOD5较其他评价因子的控制情况最差,4个监测点均呈现显著上升趋势。Monitoring water quality and analyzing its changing trend are beneficial to rational exploration of water resources.Based on the real monitoring data in the Manas River Basin in 2005,we analyzed the spatial changes of surface water quality at Manas River,Moguhu Reservoir,Daquangou Reservoir and Jiahezi Reservoir.The results showed that the water quality of Manas River Basin was the worst in the abundant water period.In addition,the seasonal Kendall test method was used to analyze the sequential changes of surface water quality from 2001-2005.The result suggested that water quality remained mainly stable,accounting to 45% of the whole changing trend.Among the water quality parameters,BOD5 was the worst,presenting obvious rising trend at four monitoring sites.
