摘要
为确定适用于淮河流域防浪林的林相结构,以已栽植的5种不同林相结构的防浪林为研究对象,分别选择南京水利科学研究院章家昌的消波性能经验公式和河海大学傅宗甫的柔性植物波高传递率公式作为乔木和灌木的消波计算公式,对5种不同林相结构防浪林的消波性能进行定量计算和理论分析。指出在淮河流域应因地制宜地选择防护林结构:在洪水起涨速率不快但高水位维持时间长的河道,宜选择单一乔木林相结构;在洪水期较长、单位时间水位涨幅缓慢、堤防整体抗冲能力薄弱的河道,宜选择复合林相的防浪林结构。
In order to determine the wave break forest structure suitable for Huaihe River Basin, the author takes five different kinds of wave break forest structures as the study object, and selects the laboratory formula from Zhang Jiachang in Nanjing IWHR and the flexible plant wave height transfer rate formula from Prof, Fu Zongfu in Hohai University as trees and shrubs wave dissipation formula, to calculate and analyze the wave dissipation performance of five different kinds of wave break forest structures in others fiver basins similar to Huaihe River. The conclusion is that in Huaihe River Basin, for the rivers with low speed of flood rising and long-time high-water level, we should choose the single tree forest type structure. And the composite wave break forest structure is the appropriate forest structure for the fiver course with long flood neriod, slow risinz rate in unit time. and weak imnact resistance embankments.
