Abstract

Sand land in the Honglianghe River area of Qinghai-Tibet Plateau is widespread, and its blown sand activity rules are currently not sufficiently understood, which is not conducive to targeted sand prevention and control work. Therefore, the dynamic environments characteristics of blown sand at Honglianghe River are investigated using different methods, such as field observation, laboratory analysis, and calculation. The direction of yearly sand-moving wind at Honglianghe River is usually found to originates from the north direction, and the sand drift potential (DP) and the resultant drift potential (RDP) are high during winter and spring, low during summer and autumn. The variation of the monthly resultant drift direction (RDD) is stable. The yearly sand drift potential is 249.84 VU, which indicates an intermediate wind energy environment. The yearly resultant drift potential is 242.92 VU, and the yearly index of directional wind variability (RDP/DP) is 0.97, which indicate a high ratio. The yearly resultant drift direction is 173.8, which indicate a south direction. The yearly total sand transport quantity of the eight directions of Honglianghe River is 434.33 kg·m-1, and the sand transport quantity of the southwest direction reached its maximum. The research results have guiding significance for controlling sand hazards of the locale.
