摘  要：
应用渭干河上游地区7个水文站点20余年的水质监测资料,探讨了渭干河上游地区各支流以及黑孜水库近10 a水质的基本状况。以2000年为例,分析了渭干河水质沿程变化和年内变化特征。利用24 a水质监测资料,分析了渭干河干流的水质变化特点。结果表明:水质类型主要以HCO3-,Ca2+型水为主,多数河流水体背景值较低,渭干河上游黑孜水库的水质近10 a矿化度以10.5 mg/(L.a)的速率上升。近24 a来,SO42-、氯硫合计浓度以及矿化度都呈明显上升趋势。在没有较大的人为污染情况下,渭干河上游地区水质能够满足下游库车、沙雅、新和地区各类用水需求。

摘  要：
Rising in the southern piedmont of the Tianshan Mountains,the Ogan River(41°06′～42°42′N,80°40′～84°10′E) was one of the headstreams of the Tarim River,which is converged by 5 tributaries including the Muzat River,Karbsyran River, Tailwankuk River,Karasu River and Hezil River,in which the Muzat River is the main tributary of the Ogan River.The Muzat River is 242 km in length,and its fall,maximum slope and catchment area are 1 637 m,23.7‰ and 16 716 km~2 respectively.In this paper,the actuality of surface water quality in the upper reaches of Ogan River and its tributaries as well as Hezil Reservoir is discussed based on the water quality data measured by more than 7 hydrological stations since recent more than 20 years,a case study on annual and seasonal change of water quality along the Ogan River is carried out,and the change characteristics of water quality of the mainstream of Ogan River are analyzed using the water quality data.The results show that the water quality is dominated by HCO_3~-and Ca~(2+),and the background values of the upper reaches of the Ogan River and its tributaries are low.The water mineralization in Hezil Reservoir has been increased with an increase rate of 10.5 mg·L~(-1)·a~(-1) since recent 20 years,and the compound concentration of HSO_4~(2-),Cl~-+ S~(2-) and mineralization has been significantly increased since recent 24 years.The results also reveal that the water quality in the upper reaches of the Ogan River can satisfy the water quality standards of all water consumption purposes if serious water pollution does not occur.
