挺水植被的状态在水流作用下会发生改变。该文通过实验室实验观测了单株挺水植被在水流作用下的状态变化和对水流阻力的影响，分析了不同水流条件下单株挺水植被状态和阻力系数之间的关系；同时研究了相同水流条件下不同种类或生长期的挺水植被对水流阻力的影响。研究结果表明，挺水植被相对刚度和阻力系数之间关系密切，随着相对刚度的增大，阻力系数也随之增大。

The state of the emergent vegetation is varied with different inflow conditions. In this paper, the state and the resistance of individual emergent vegetation are observed in the laboratory. The relationship between the state and the drag coefficient of individual emergent vegetation is analyzed under different inflow conditions. The influences of the various emergent vegetations on the flow resistance are discussed under the same inflow conditions. The result is shown that the drag coefficient increases with the increase of the relative bending rigidity of the emergent vegetation.
