摘要

集沙仪是定量监测风沙活动的重要工具。设计了一种自动连续称重式集沙仪,可以根据试验需要采集不同高度沙样,每分钟收集一次质量数据,实现高频连续集沙。试验结果显示,自动连续称重式集沙仪在15、30、60 cm高度的集沙量满足随高度增加呈指数减少的规律;在15 cm高度,风速与输沙通量呈指数函数关系(y=6E-05·e0.8417xR2=0.6042),随集沙高度升高输沙通量与风速相关性减弱。自动连续称重式集沙仪与新型平口式集沙仪所测的输沙通量具有很好的一致性(y=0.8119x+0.2645,R2=0.7481)。自动连续称重式集沙仪虽然在稳固性方面需要改良,但能够很好地捕捉高度在15 cm以下沙物质的输移信息,野外应用效果良好, 是一种适合野外高精度风沙活动自动监测的新型测量工具。

Abstract

Sand collector is important to quantitatively monitor aeolian sand activities. In this research, a cyclone type continuous-weigh sand trap was designed. This sand trap was further investigated for farmland environment during a storm in the Kangbao County of the agro-pastoral ecotone of northern China. The results showed that the cumulative sediments weights of the cyclone type continuous-weighing sand trap at heights of 15, 30, and 60 cm exponentially decreased with the increase of collecting heights. Significant exponential relationship between the sediment flux and wind speed was observed for the inlet at the height of 15 cm(y=6E-05·e0.8417x, R2=0.6042), but the correlation coefficients between sediment flux and wind speed decreased with the increase of the inlet height. Comparison of the sediments flux measured by the cyclone type continuous-weighing sand trap and that by the new flat opening collector showed that sediments flux of the new flat opening collector were closely related to that of the cyclone type continuous-weighing sand trap's(y=0.8119x+0.2645, R2=0.7481). Although the cyclone type continuous-weighing sand trap requires improvement in stability, it is able to capture the aeolian sand flux below 15 cm at 1min time scale.
