摘要: 基于SELFE的珠江河口3D数学模型,统计了珠江河网河口湾的能量通量与能量耗散。从能通量和能耗分布特征看,珠江河口可以分为伶仃洋虎门水域、磨刀门河口水域区、黄茅海潭江水域、网河区水域。潮能通量与耗散特征与珠江口滩槽地形分布特征大体一致。上述各区域存在‘门’等高能耗局部地貌单元,其单位面积能耗比附近水域的高数倍甚至1~2个数量级。

Abstract: Based on a 3D hydrodynamic model developed on SELFE, the tidal energy fluxes and dissipation of the Pearl River estuary were discussed. The results showed that the tidal energy flux distribution corresponded to the topography beneath water in the estuary, and the Pearl River estuary can be divided into four zones: LingdingyangHumen zone, Modaomen estuary zone, HuangmaohaiTanjiang zone, and river net zone. There existed a hot spot zone (called “men” in Chinese) with high energy dissipation, about 1~2 order magnitude higher than the nearby water area, in these zones.

Key words: the Pearl River delta, estuary, tidal energy flux, dissipation
