西沟孔兑下垫面特征及风沙输移规律研究
Study on The Characteristics of the Underlying Surface of Xiliugou Hole and The Law of Aeolian Sand Transport
黄河上游十大孔兑对黄河生态和周边地区发展存在严重威胁。通过样方调查划分下垫面类型和利用集沙仪和 HOBO 小型数采仪配套三杯风速仪及风向标对各个下垫面的输沙量和风速、风向进行观测,对十大孔兑之一西柳沟风沙区展开研究,探究该地区不同下垫面特征及风沙输移规律,为相似流域保护与治理提供参考依据。结果表明:(1)西柳沟孔兑风沙区下垫面划分为流动沙地、半固定沙地和固定沙地,流动沙地河床面积、长度和宽度均高于固定和半固定沙地。(2)研究区盛行风均为西南风,主…查看全部>>
The ten major Kongdui in the upper reaches of the Yellow River pose a serious threat to the ecology of the Yellow River and the development of the surrounding areas.Through the sample survey,the type of the underlying surface was divided and the sand collecting instrument and HOBO small data collection instrument were used to observe the sand transport volume,wind speed and wind direction of each underlying surface,and the wind and sand area of Xiliugou,one …查看全部>>
