摘 要:黄河治理在元朝并未获得重视,治河也没有任何显著成效,仅元末至正十一年(1351年),由贾鲁领导的一次治河活动获得了巨大成功,影响深远。通过对贾鲁治河的背景、工程过程及对工程效果的初步研究,更加全面、客观地理解那次治河活动的意义,可为今日治河提供有益借鉴。In the Yuan Dynasty, regulation of the Yellow River had not been attached great importance until the end of Yuan Dynasty to 1351, during which great achievement was made by Jia Lu that had exerted far- reaching impact to the present. Based on preliminary studies on the background, process and effect of river harness projects, comprehensive and objective significance has been reached regarding to the importance of Jia's contribution, which can be referenced for current river regulation.
