What is the terrain of Lanzhou?

The terrain of Lanzhou belongs to basin-like terrain, and there is a long and narrow Lanzhou city between the north and south mountains. This valley topography leads to the zonal distribution of Lanzhou, with a long distance from east to west and a short distance from north to south. The overall terrain is high in the west and low in the east, which belongs to the transition zone from the first Qinghai-Tibet Plateau to the second Loess Plateau in China. I hope the answer will help you. Please keep asking questions. Thank you.
