北宋时期 ,河北路的御河在当时是一条较为重要的内陆运河 ,它是由隋唐时期的永济渠发展而来的。在北宋一代南北对峙的局势下 ,御河的河运之职得到了充分发挥 ,北宋政府通过它运输物资赴河北边地养兵防边。御河作为漕运渠道 ,其功能的最终消失是由于黄河侵占其河道所造成的。本文试图对北宋一代御河的水源、作用及淤废等问题作初步探讨 During the Northern Song Dynasty, the Yuhe River at Hebei Road was a more important inland canal at that time. It developed from the Yongji Canal during the Sui and Tang Dynasties. Under the situation where the North Song Dynasty was confronted by the North and South Dynasties, the river transport of the Yuhe River was given full play. The Northern Song Dynasty government, through it, transported goods and materials to the border areas of Hebei for support and prevention. Yu River as a canal, the ultimate disappearance of its function is due to the Yellow River invaded its channel caused. This paper tries to make a preliminary study on the source, effect and siltation of the Yu River in the Northern Song Dynasty
