摘要: 沙丘的共生,指的是不同类型的沙丘能够在同一片区域某一个时间段同时存在。对柴达木盆地的5处新月形沙丘和线性沙丘共存区域进行分析研究,结果表明这种共生沙丘一般都发育在沙源不足的高山、湖泊的边缘,而且发育在常年单一风向条件下;都是发育小型沙丘,很少有大型的共生沙丘;新月形沙丘和线性沙丘发育没有固定的方位模式,但都是沿着主风向发育,发育的相对位置与障碍物的方位有很大的关系;风况对共生沙丘的发育也有很大的影响。

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
