中文摘要：

为研究天然湿地灌木植被群落交错区植被特征参数垂向变化对水流流速垂向分布的影响,进行了室内实验。在室内水槽种植灌木植被和灌木-草本植被,沿纵向方向设置5个监测断面,垂向布设若干测点,利用Doppler流速仪测量纵向流速,比较分析单一灌木植被群落和群落交错区内纵向流速垂向分布规律。结果表明：植被之间水流纵向流速垂向分布近似为双曲线;植被冠层以上流速垂向分布符合幂函数曲线。

英文摘要：

The effects of vertical changes in the vegetation characteristics on the vertical flow velocity distribution were studied in a natural wetland ecotone modeled by shrubs mounted in a flume with five velocity profile measurements in the longitudinal direction. Longitudinal flow velocity was measured by a Doppler flowmeter. The results show that the vertical distribution of the longitudinal velocities in the single shrub community is approximately hyperbolic inside the shrubs and follow a power function above the shrubs.
