摘要

在库姆塔格沙漠羽毛状沙丘分布区选取典型地段作为观测区,运用全站仪测量了观测区羽毛状沙丘地形特征。结果如下:(1) 构成羽毛状沙丘羽轴的沙垄由首尾相连的变形的新月形沙丘构成,其走向为N55°E;新月形沙丘的平均高度为17.65 m,西北翼角的平均长度为72 m,均长于东南翼角。(2) 沙垄的纵断面(SW→NE)表现出明显的波动性,波长在50~100 m之间,波高在10~25 m之间。(3) 沙垄的平均宽度为127.69 m,平均坡度为12.59°;西北坡平均坡长为71.74 m,平均坡度为11.65°,东南坡平均坡长为59.05 m,平均坡度为13.52°。(4) 羽毛状沙丘的“羽枝”部分是由地形平缓的穹状大沙波首尾相连构成,并未像遥感影像一样呈现出明暗相间的羽毛状图案。大沙波的平均宽度为641.34 m,其纵断面相对平缓,2个波峰之间的距离在400 m左右,波峰高度为1~3 m,平均坡长为322.37 m,平均坡度为1.28°,仅为沙垄的10%。

Abstract

Feather-like dunes was named from its feather-like shape. In this paper, topographical features of feather-like dunes was measured by total station instrument in the Kumtagh Desert, and the profile characteristics of feather-like dunes was analyzed. (1)The direction of "quill" of feather-like dunes was N55°E, and the "quill" was composed of crescent dunes ridges with the average height of 17.65 m, and the average length of northwest wing was 72 m, longer than southeast wing. (2)Great fluctuation was found from the profile of the "quill", the wave length was 50-100 m, and the wave height was 10-25 m. (3)The average width and slop of the "quill" were 127.69 m and 12.59, respectively. The average length and slop of northwest slope were 71.74 m and 11.65, respectively. The average length and slop of southeast slope were 50.09 m and 13.52, respectively. (4)The "plume" of feather-like dunes was composed of large dome sand dune waves, not a feathery pattern of light and dark as remote sensing image showing. The average width of the large dome sand dune waves was 641.34 m, and the profile was relatively flat. The distance between two sand waves was about 400 m, and the wave height was about 1-3 m, the average slop length and average slope were 322.37 m and 1.28, respectively.
