对宽滩和窄滩河槽的过流能力以及滩地种树的的漫滩水流水力特性进行了研究表明:像珠江三角洲网河这样的窄滩复式河槽,滩地种树对水位的影响不大,也不会影响滩地的槽蓄滞洪作用;但种树使滩地水流归槽,主槽流速增大;滩地种树的利和弊及对行洪的影响是多方面的,应视具体情况分析 The study on the over-flow capacity of wide-bounded and narrow-trough fluvial channels and the hydraulic characteristics of floodplain-typed floodplain shows that, for example, the narrow-trenched double-channel fluvial network such as the Pearl River Delta in the Pearl River Delta has no significant effect on the water level, It will not affect the trough storage and detention effect of the beach land. However, the planting of trees causes the flow of water from the beach land to the trough and the flow velocity of the main trough to increase. The pros and cons of planting trees and their impact on flood discharge are numerous and should be analyzed as the case may be
