摘　　要：选择了30个有代表性的全沙输沙强度计算公式,利用超过5000组水槽和天然河道实测资料,全面客观地比较了这些公式在天然均匀沙时的床沙质输沙浓度的计算精度。结果表明:Karim Kennedy,Engelund Hansen,Ackers White,Brownlie,Peterson Peterson,Basson,Yang,王士强等公式,是几个值得推荐使用的公式,可供有关泥沙研究人员参考。30 representalive equations of total sediment transport rate are selected.By using more than 5000 sets of measured data in flums and natural rives,the sediemt concentration computed by these equations has been compared with measured data compregensively and objectively in the condition of natural uniform sediment.The results show that the equations proposed by Karim-Kennedy,Engelund-Hansen,Ackers-White,Brownlie,Peterson-Peterson,Basson,Yang,Wang Shiqiang,et al.,can be recommended for use.These results can be referred by sediment researchers.
