基于理论推导及其简化处理，并结合部分水槽试验资料的回归分析，建立了明渠植树后床面相对切应力、糙率与树木因子ＦＶ之间的计算关系，为进一步探讨植物滞流拦沙的机理奠定了基础
Based on the theoretical derivation and simplified treatment, combined with the regression analysis of some sink test data, the relationship between the relative shear stress and the roughness factor of bed and the tree FV was established. In order to further investigate the relationship between plant stagnation and sediment retention Mechanism laid the foundation
