摘 要:通过对河西不同区域戈壁水文资料的调查和对采集水样水质的检测分析表明:河西走廊戈壁水质总体良好.从戈壁不同的分布区域水质分级来看:党河流域中下游戈壁、黑河流域中下游戈壁水质以Ⅰ类较好的水为主,未检测出Ⅲ、Ⅳ类水.疏勒河流域中下游、北山黑戈壁区域水质相对下降,均有Ⅲ类水检出.石羊河流域下游戈壁水质以Ⅱ类中等水为主,Ⅰ类较好的水比例降低,但是总体上水质良好.The hydrological data in the gobi areas of water samples collected therein were analyzed. of Hexi Corridor were surveyed and the water quality The results showed that water quality in the gobi areas of Hexi Corridor was generally fine, while it was of a different quality in different areas. The gobi in the lower reaches of Danghe River and Heihe River were dominated with class Ⅰ water, while Ⅲ and Ⅳ were not found. Water quality in the gobi areas of the middle and lower reaches of Shulehe River and Beishan Mountain were relatively bad, where the class Ⅲ water had been detected all. The gobi area in the lower reaches of Shiyang River was dominated by class Ⅱ and there was less of class Ⅰ water. In general, the water quality was fine.
