蜿蜒型河道成因问题不仅对于河床演变学科具有理论意义，在生产上也有实践意义，对整治河道、防止河道剧烈演变也有一定的实际指导作用。 蜿蜒河道是自然地形决定的。地球是凸凹表面．有高山、丘陵、高原、平原、盆地等自然地形，水流动的自然规律是从高处向低处流动。大地的高 The origin of the meandering river is not only of theoretical significance for the evolution of the riverbed, but also of practical significance in production. It also has some practical guidance to rectify the river and prevent the dramatic evolution of the river. Winding river is determined by the natural terrain. Earth is convex surface. There are mountains, hills, plateaus, plains, basins and other natural terrain, the natural law of water flow is from high to low flow. The earth is high
