Aeolian-Sand Flow Structure at Different Locations along Desert Highway Shelterbelt
摘要
Abstract
In this paper, BSNE sampler was used to study Aeolian-sand flow structure in ground layer along both shelterbelt sides of a desert highway.The results are as follows:① The Aeolian-sand flux at the upper part of shelterbelt trended to accordance with the increase of height at different positions of shelterbelt.The difference of Aeolian sand flux at different observation sites occurred mainly in the ground layer.Vegetation and its coverage had a decisive effect on Aeolian-sand flux in the ground layer.Aeolian-sand flux along the shelterbelt was in an order of windward side ＞ quicksand land ＞ inter-shelterbelt zone ＞ leeward side ＞ shelterbelt;② The Aeolian-sand flux on windward side of the shelterbelt and quicksand land was mainly distributed within 20 cm height from the ground surface,and that on leeward side of the shelterbelt was mainly distributed within 50 cm height,which accounted for over 74％ of the total Aeolian-sand flux within the observation height.The Aeolian-sand flux in the inter-shelterbelt zone and the shelterbelt was relatively uniform and varied in a range of 11％-23％;③ The difference of vertical distribution of Aeolian-sand flux outside of the shelterbelt windward side, leeward side and quicksand land was very high,the Aeolian-sand flux was decreased with the increase of height in a power-function way, but it was in a decrease trend in the shelterbelt, and the Aeolian-sand flux was decreased at first and then increased with the increase of height in a polynomial-function way.关键词
