| 摘 要： | 实测了模型芦苇丛中流速沿水深的变化，结果表明流速为常数的假定是可以接受的；基于流速为常数，在理论上得到了植株密度和糙率的关系，实验结果证实了它是正确的；实验结果还证实了在试验的芦苇密度范围内单株的综合租力系数和植株密度无关，并给出了CD和n的换算关系。

| Abstract: | The variations of the velocities through cross sections have been measured by a experimental approach, and the results present that we can theoretically assume the velocities are invariable. Based on the invariability of velocities, it is confirmed by these results of experiments that the relationship between the density of reeds and roughness coefficient n got in theory is in reason, and these results also approve the resistance coefficient CD Of one single reed is independent of the density of reeds , and then the relationship between CD and n is deduced in the paper. |
