Topography and geomorphology of Luzhou

Luzhou city is a typical mountainous city with 56.14% of the total land area. It is mainly composed of high mountains (500-1000 meters above sea level) and middle mountain (1000-1902 meters above sea level). Taking the middle Yangtze River Valley as the lowest center, it gradually rises to the north and south sides. The lowest elevation of the Yangtze River Valley is 203 meters (on the surface of Guanqiao village, Lujiao County, Hejiang River), which is the center of the convergence of geomorphic erosion base level and runoff from the north and south banks of Luzhou area. On the north bank, the highest is Wanshou mountain, with an altitude of 757.7 meters; on the south bank, the highest is Muyu mountain in luohanlin, Xuyong County, with an altitude of 1902 meters. The north and south banks are asymmetric saddle shaped, with a height difference of more than km. In addition, the similarities and differences of the geomorphic outlines between the northern and southern banks lie in the fact that the Yunnan Guizhou Plateau is in the south, with low and medium mountains as the main part, and the mountains are compact and the flat land is few, and the height rises gradually to 1902 meters. In addition to the gentle hills and valleys in the northern part of Sichuan Province, the landform is gentle and gentle, and the mountains and valleys in the north are gentle and gentle.
