Ma Wang's satellite map
(including longtan town and Ganxigou), the dam elevation is about 200~300m. The eastern part is a hilly area with an altitude of 400 m ~ 600 m in Haibo, and the western part is a watershed alpine area with an altitude of 800 m ~ 1000 m in Haibo (the western part is Wujiang River system, while the eastern part where Mawang is located is unitary water system). All the mountain systems belong to the Great Wuling Mountain System, which is the transition area from Yunnan-Guizhou Plateau to the middle and small plains of the Yangtze River, so there are running rivers and certain vertical vegetation distribution in the area.
