本文根据乌鲁木齐河流域内主要控制站的多年水文资料,从气温、降水、径流、洪水等方面对流域的水文特性进行了分析,并于2009年11月对乌鲁木齐河上游进行野外水样采集,对上游水质进行实验研究.结果表明,乌鲁木齐河上游水体矿化度不高,含盐量均为≤500mg/L,总硬度为145～175mg/L,PH值在7.0～8.2之间,电导率为250～350uS/cm,高锰酸盐指数含量较低,六价铬未检出.按地表水环境质量标准,(GB3838-2002)上游的水质良好,属Ⅱ类水域.
Based on the multi-year hydrological data of main control stations in the Urumqi river basin, this paper analyzed the hydrological characteristics of the basin from aspects of temperature, precipitation, runoff and floods. In November 2009, the water samples were collected from the upper reaches of the Urumqi River. The results showed that the salinity of the upper reaches of the Urumqi River was not higher than 500 mg / L, the total hardness was 145-175 mg / L, the pH value was between 7.0 and 8.2 and the conductivity was 250 ~ 350uS / cm, the content of permanganate index is low and the hexavalent chromium is not detected.According to the surface water environmental quality standard (GB3838-2002), the water quality in the upper reaches is good and belongs to the class Ⅱ waters.
