Investigation of Qi Water Conservancy Project in Mingzhou of the Song Dynasty
In the Song Dynasty,the water conservancy projects in Mingzhou were mostly made of stone materials,which could not only prevent the flooding of rivers and lakes and control waterlogging,but also utilize fresh water to wash coastal brine soil and reduce the concentration of alkali brine,which had significant water conservancy benefits.The Qi water conservancy projects,together with small and medium-sized water conservancy projects such as seawalls,lakes and weir gates,constituted an effective water conservancy network,which provided a strong support for the local farmland irrigation,promoted the improvement of agricultural productivity level,and laid a foundation for the social and economic development of Mingzhou in the Song Dynasty.
