Abstract

Abstract:

By conducting wind tunnel experiment on soils of three typical habitats （mobile dune， sandy grassland， and farmland） in the Horqin Sandy Land， the sand flow structure， sediment transport rate， and total sediment transport amount were analyzed under different soil water contents. The results showed that：（1） The sediment transport rate of three soil types decreased with the increase of height under different water content， and had a good exponential function relationship. （2） With the increase of water content， the average jump height of wind-quicksand for the soils of mobile dune and sandy grassland increased， and the ratio of sand transport rate of 0-12 cm to total sediment transport rate increased， while the soil of farmland showed the opposite trend. （3） The relationship between sediment transport amount and water content at different wind speeds for three types of soil can be described as an exponential function or a cubic function relationship. （4） Based on the variation degree of sediment transport amount with the increase of water content at different wind speeds， the water content can be divided into three sections： stable decline interval， jump interval， and weakening interval. The jump interval of soil water content of mobile dune， sandy grassland， and farmland was 0.79%-1.01%， 1.14%-1.72%， and 2.77%-4.44%， respectively. （5） With the increase of soil water content， the order of total sediment transport amount changed among the soils， which was mobile dune > sandy grassland > farmland at the range of 0.00-0.76%， sandy grassland > mobile dune > farmland with at 0.76%-1.35%， and farmland > sandy grassland > mobile dune with the water content above 1.35%.

Key words: sand flow, water content, wind erosion, wind tunnel, Horqin Sandy Land
