摘要: 本文根据沙坡头、龙羊峡两地风洞和野外输沙率的实测数据, 对风速与输沙率进行了统计处理, 着重分析风洞与野外输沙率的差异及其原因, 并提出用风洞模拟实验输沙率去估计和代替野外输沙率的方法。
Abstract: The small-scale modeling of sand-transport ratio in Wind-tunnel exer-iment has provided with a significance position on studying and combating desert and desertification. By using the measures of mathematical statistics, we have made a tentative analysis for the modeling sand-transport in wind-tunnel at Shapotou and Longyangxia areas, and the observation data for the sand-transport ratio in feild. The result confirmed that,in general,the sand-transport experimental values in wind-tunnel is greater than 2 m hight of sand-transport values under same wind velocity condition in feild,and the sand-transport ratio value in wind tunnel experiment couldn't substitute directly for the value in feild.But after calculatingnd the wind velocity ,using concerning equation between wind velocity and satransport ratio,the data obtained from modeling of sand transport ratio in wind-tunnel can replace the sand-transport ratio under the identical condition in feild.
