摘　　要：近年来,陕北天然气石油资源的开采利用,城市规模和人口数量的迅速膨胀都对延河和清涧河的水质造成很大危害,影响到延安市居民的饮水安全。对延安市水源地王窑水库上游的石油泄漏事件进行了分析,并对延安市主要河流延河及清涧河的地表水进行了系统的采样测试和分析评价。在16项检测项目中,认为影响该流域水质的主要污染因子为石油类、挥发酚、COD、TP、氨氮,并指出了这些污染因子在不同区域的污染现状。认为造成该地区地表水质污染的主要原因是含油废水的非法排放、石油泄漏事故,不合理的化肥施用以及未经处理的生活污水随意排放。With the growth of development of nature gas and petroleum resources exploitation in the northern ShanXi, the expansion of city and the growing population, the water quality of YanHe River and Qing JianHe River is severely affected. The drinking water for citizens in Yan＇an city is becoming unsafe. We analyzed the accident of petroleum pollution taking place in WangYao reservoir, the source of drinking water for Yan^n city, sampled and tested the surface water of Yanhe River and Qingjianhe River, the main rivers of Yan＇an. Among 16 test items, we considered petroleum, volatile phenol, COD, TP, ammonia nitrogen are the main pollution factors that affect this area. We also figured out the current fact of these pollutions in variable areas. A conclusion can be drawn that the pollution of surface water in this area is caused by illegal dispose ef waste water that contains petroleum substance, the accident of petroleum leaking, irresponsibly using of chemical fertilizers and unlimited emission of waste water by citizens.
