摘　　要：简要叙述了国内外集沙仪的研究现状,结合目前在土壤风蚀研究中使用的多种不同形式的集沙仪无采样性能的标定,对采集数据的影响很大,由此造成根据采样数据研究得出的土壤风蚀规律不一定能够反映真实情况。为此,针对近床面区集沙效率是研究集沙仪性能的关键,探讨了影响集沙仪采集性能的主要因素:排气口面积、排气口位置、进沙口的高宽比和进沙通道的长度参数。This paper briefly describes the domestic and international Sand sampler of the status quo, Combination of soil erosion in the current study used a variety of different forms of Sand sampler without sampling performance of calibration, Collecting data on the impact of large, According to the resulting data sampling study of soil erosion laws do not necessarily reflect the true situation. Sand sampler missed the mainly occurred in the area near the bed. Near the bed sand collecting efficiency of the issue is to research Sand sampler Sand efficiency of the key. Impact of proposed Sand sampling performance of the main factors： exhaust port area, exhaust position and Shakou the ratio of height to width, sand into the channel length.
