摘要

对中国陕西省北部地区的榆林和靖边地区沙丘运动进行了评估。结果表明榆林和靖边地区总移动沙堆分别达24.433和21.147t。平均沙丘移动速率分别为4.61m和3.99m

而每月沙丘在榆林和靖边分别前进1.152m和0.997m。受影响最大的月份是6月份

接下来的是7—9月份。沙丘运动依赖于风速、沙丘高度、沙丘长度以及坡度。研究表明开垦地与沙丘方向相交时

受到极大影响

而与沙丘平行时

不受影响。

Abstract

This investigation was conducted to estimate sand dune movement in Yulin and Jinbian areas of northern Shaanxi Province

China

Results indicate that total sand movement has been 24.433

21.147t for Yulin and Jinbian

respectively.The mean sand dune movement equates to a rate of 4.61 and 3.99m per year

but average monthly sand dune movement rates were 1.152 and 0.997m for the two locations respectively.The rates of movement occurred in Jul.follwed by Jun.

Aug.and Sep..Rates of movement depend on wind velocity

dune height

and dune length and slope ratio.The study reveals that cultivated lands extended obliquely to the direction of sand dune movement are extremely affected severely by the movement

while cultivated land segments extending parallel to the direction of movement are not affected.
