水深与刚性植被高度的相对关系对防浪林消浪效果的影响

Influence of the Relative Relationship between Water Depth and Height of Rigid Vegetation on Wave Dissipation Effect of Wave Break Forest

用刚性防浪林相对水深综合表征水深与植被高度的相对关系,通过设计模型试验研究不同相对水深条件下刚性防浪林消浪效果的变化规律,分析波浪衰减系数与相对水深之间的关联,探究相对水深在防浪林建设规划中的参考意义,据此设计老龙口堤段刚性防浪林的合适树型。结果表明,水深与树干、树冠高度的相对关系均在不同程度上影响防浪林消浪效果。参考相对水深,选出合适高度比例的刚性植被营造防浪林,可以充分发挥植被对波能的衰减作用。

The relative relationship between water depth and vegetation height was comprehensively expressed by the relative water depth of rigid wave break forest,a model test was designed to study the wave dissipation effect of rigid wave break forest under different relative water depths,to analyze the correlation between wave attenuation coefficient and relative water depth,to explore the reference significance of relative water depth in the construction planning of wave break forest,according to model test results,the suitable tree type of rigid wave break forest in Laolongkou dike section was designed.The results showed that the relative relationship between water depth and the height of tree trunk and crown affected the wave dissipation effect of wave break forest to some extent.According to the relative water depth,choosing the rigid vegetation with appropriate height ratio to build the wave forest could give full play to the attenuation effect of vegetation on wave energy.
