摘要
珠江三角洲是在浅海湾内的多河道上淤积而成的,其流域水系景观具有鲜明的地域特征,从水系结构特征、水情特征、水系景观的地域特征3个方面总结了珠江三角洲流域水系景观的特征,并通过问题缘由、客观数据及形态表征的相关分析,概括出珠江三角洲流域水系景观存在的结构性问题:1)干流收窄,河床演变加剧;2)河涌减少、河网密度降低,湖泊水面缩小;3)围垦收窄河口,加重淤积,洪涝加剧,为该区域水系景观规划提供了基本依据。
The Pearl River Delta was silted up on the shallow bay multi-river courses, and its basin river system landscape has the intensive regional characteristic. In this paper the Pearl River Delta basin river system landscape characteristic is summarized from three aspects： the river system structure characteristic, the state of water characteristic, the river system landscape regional characteristic and so on. Through the reason, the objective data and the shape altribute correlation analysis, the existing structural problems of the Pearl River Delta basin river system landscape are summarized： 1] the main stream is narrowing, and the evolution of riverbed is severe; 2] the river volume is decreasing, the densily of river network is lowering, and lake surface is decreasing; 3] the estuary is narrowed by reclamation, which makes siltation and flood more serious. This provides fundamental basis for the river system landscape planning of this region.
