Dawu headwaters ground is the uncommonly oversize headwaters ground in the north and it is very important to economic development and society stabilization of Zibo city. However, since it has been exploited,a series of problems,such as continuous descent of ground water level and serious pollution of water quality in partial district, appeared with the fast increment of water use scale. In this article,the exploitation and utilization status of ground water and dynamic change rule of water level are analyzed deeply,and the cause of foundation and space-time distributing characteristic of petroleum pollution is discussed. The method and indexes of water quality assessment are chosen, and water quality status of the space-time sections in Dawu headwaters ground is synthetically assessed. In the end, the rational suggestions on water resources sustainable utilization are put forward.%大武水源地是我国北方罕见的特大型地下水源,它对淄博市的经济发展和社会稳定起到决定性的作用,然而自水源地投入使用以来,随着用水规模的迅速增加,相应出现了地下水位持续下降、局部地区水质严重污染等一系列问题.在对水源地地下水的开发利用现状和水位动态变化规律进行深入分析后,研讨了地下水中石油类污染的成因和时空分布特征,并选取多级关联水质评价方法和评价指标,对水源地各时空断面上的水质状况进行综合评价,给出水资源可持续开发利用的合理化建议.
