Chinese Tradition as the Fundamental Structure and Western as the Application:The Progress of Water Conservancy Technology in Ningxia during the Yuan and Ming Dynasties
The Yellow River diversion irrigation area of Ningxia has a long history and has been irrigat-ed for thousands of years.From the Qin and Han Dynasties to the Tang dynasties,Yinchuan Plain was gradu-ally built the canals of seventh grade(Qin Jia)and Hambo in Hedong area,and the canals of Han Yan and Tang Lai in Hexi area,and the Li Wang Canal in the Western Xia Dynasty.Before the Mongol Yuan Dynasty,the channel sluice used wood and stone,and the rest were built with earth dam.In the Tang and Western Xia Dynasty,bundles of branches were used to build canals and dams,which were covered with sand.Willows were planted on the sides of the dams and roots were used to consolidate the dam foundation.However,tradi-tional technologies could not solve a series of problems caused by the development of water conservancy in Ningxia.According to historical speculation,After Mongolia's westward conquest,Central Asian water con-servancy technology gradually spread to the east.Through the Yuan Dynasty and the early Ming Dynasty,and continuously integrated into Ningxia,to complete the"change wood for stone"material update and increase the"dark hole,flying trough,bottom stone"technical change in the late Ming Dynasty.Throughout this pro-cess,it can be described as the typical integration of traditional Yellow River diversion irrigation and western technology,to promote the new progress of water conservancy technology in Ningxia.
