Abstract

Abstract: The symbiotic dunes refer to the coexistence of different types of sand dunes in the same area. We found, based on the study of the coexistence of crescent dunes and linear dunes in the Qaidam Basin, the symbiotic dunes are usually developed on the edge of the mountain or lake where sand is lack, with perennial single wind condition. The symbiotic dunes are usually relatively small, and there are few large symbiotic dunes. In the Qaidam Basin, there is not fixed mode for the development of crescent dunes and linear dunes, except along the main wind direction. The position of the symbiotic dunes is related to the direction of the obstacles, and the wind condition has great influence on the development of the symbiotic dunes.

Key words: Qaidam Basin, symbiotic dune, crescent dune, linear dune
