The stratum of Zhangjiajie city is complex and diverse, which has created the local characteristic landscape. There are mainly mountains, karst, hills, hills and plains. The mountainous area accounts for 76% of the total area, among which the most distinctive is the rare seasonal sandstone peak forest landform in the world. The city is high in the northwest and inclines to the southeast along the Lishui River.
Another outstanding performance of the urban area is that due to the rising of the earth's crust, the streams are cut down and enlarged, and it is too late to widen the rivers, resulting in valleys and canyons. The bottom of the river is very linear, with steep walls and the beach is full of water. The headwaters of Lishui, upstream of backwater and Mao Yan reach in Zhangjiajie City are valley landforms.
