摘　　要：研究一维全沙泥沙输移 (悬移质泥沙和推移质泥沙 )数学模型及其应用 .文中对比了国内外常用模型的特点 ,结合笔者在一维全沙泥沙输移数学模型计算中的经验 ,分析各模型的差异 ,特别是针对模型中有关参数的选择进行讨论和分析 ,在此基础上建立一维全沙泥沙输移数学模型 SFST-1D.并将该模型分别应用于深圳河治理环境评价、波迪D mathematical model for total sediment transport (suspended load and bed load) and its application have been presented in this paper. Both of Chinese numerical simulation and the West one have been compared. As a result, some of key parameters in the models have been described and determined. The model SFST 1D has been used in the environmental impact assessment study on Shenzhen river regulation project and the deposition calculations of sedimentation on Bodi Kexi project.
