摘　　要：灌丛沙堆是干旱、半干旱地区一种常见的景观特征,其形成标志着该区域存在土壤风蚀和土地退化现象,也是荒漠化现象的一种表现形式,在我国分布较广。该文基于荒漠化草原的研究,主要从风积物与灌丛沙堆之间的关系、不同发育阶段藏锦鸡儿灌丛沙堆形态等几个方面进行研究,并提出藏锦鸡儿灌丛沙堆研究的发展趋势。灌丛大小不同表示着发育阶段的不同,其沙堆形态也不一样,影响沙堆形态的主要因素是风蚀力作用下沙源量,灌丛大小和沙堆形态之间存在线性相关。藏锦鸡儿灌丛沙堆在风蚀力和沙源等因素的共同作用下,灌丛沙堆间的整体协调发展表现出多样的形态特征。Nebkha is a common landscape feature in arid and semi-arid regions.The formation of nebkha in some areas is a sign of soil wind erosion and land degradation,and is also a manifestation of desertification,which is widely distributed in China.This paper is based on the study of desertified grassland,mainly from the relationship between the wind accumulation and nebkha,the different development stages of the Caragana tibetica morphology and other aspects of the study and put forward the development trend of the study of the Caragana tibetica.Different sizes of scrub indicate different developmental stages,and the morphology of the sand pile is different.The main factor affecting the morphology of the sand mound is the amount of sand source under the action of wind erosion,and there exists a linear correlation between the size of the scrub and the morphology of the sand mound.Under the joint action of wind erosion force and sand source,the overall co-ordinated development of the sand piles among the scrubs in the Caragana tibetica nebkhas showed various morphological characteristics.
