Research of Sand Drift Potential and Wind Conditions in Xilamuren Grassland

Abstract:

Using the wind data in Xilamuren desert grassland by wind erosion monitoring system to record the years of 2011-2013 as the research foundations, through the statistics of wind and sand transport potential research, from aspect of the characteristics of blown sand environment Xilamuren desert grassland which can be shown the research area are mainly affected by the westerly, Northwest westerly wind or northwest wind three group interaction. The study area of annual sediment potential had mainly effected by westerly and Northwest westerly wind direction ,with wind direction variability index in 0.51°~ 0.61°, belonging to the intermediate ratio range of direction. Annual sediment potential was between 135.95VU ~214.1VU,belongs to the small and medium-sized wind environment. The spring sand transport potential and the resultant sand transporting potential than the other three seasons of sediment transport potential and the resultant sand transporting potential, the main direction of resultant sand transporting potential to Northwest westerly direction, wind direction variability index is relatively large. For spring grassland vegetation coverage rate is lowly, wind speed is large, characteristics of sand is belong to rich material, which should we to retain sand material through the appropriate protective measures to reduce wind erosion. So analyzing the wind regime and the theory of sediment transport potential calculation, provide scientific theoretical basis for the prevention and treatment of sand and harm to the Xilamuren grassland sand flow process.
