摘　　要：通过对山东省特别是鲁北地区引黄发展过程的研究,定量分析了鲁北地区大规模引黄灌溉前后地表径流系数的变化。结果表明,降雨量基本相同时,区域地表径流系数随引黄量的增大而增大。同时,大规模引黄灌溉后,增加了对浅层地下水的补给量,并且成为浅层地下水的主要补给来源。可利用黄河水替代深层地下水,控制和停止开采深层地下水或回灌深层承压含水层,能缓解淡水地下水漏斗扩大的问题。The change of surface runoff coefficient of North Shandong before and after large-scale irrigation diversion from Yellow River was quantitatively analyzed by discussing the development process of Yellow River diversion in Shandong Province, particularly in North Shandong area in this paper. The results showed that in condition of similar rainfall, the regional surface runoff coefficient increased with the increase of diversion amount from Yellow River. Meanwhile, after large-scale Yellow River irrigation, it became the main recharge source of the local shallow groundwater. Yellow River water could be used instead of deep groundwater, controlling and stopping the deep groundwater over-exploitation or recharging the treated Yellow River water into deep confined aquifer, which could ease the problem of the freshwater deep groundwater cone enlargement. In short, Yellow River irrigation could bring huge benefit to eco-environment, and play an irreplaceable support role in the sustainable socio-economic development of Shandong Province.
