【摘要】 <正> 广州地处广东省中部,包括广州市区、郊区、黄埔以及清远、佛冈、新丰、龙门、增城、从化、花县、番禺8个郊县。主要河流有珠江、流溪河、增江、滨江、潖江和新丰江。其中珠江、流溪河、增江、滨江和潖江的流域面积均超过1000平方公里。流域面积100～1000平方公里的河流有65条。山区河流众多,河床比降大,水力资源丰富。南部为珠江三角洲河网,河网密度平均1公里/平方公里左右。在华夏系与新华夏构造的控制下,广州几条主要河谷均沿构造线发育,形成以北东更多还原

【Abstract】 The relationship between the shape of the fiver basin and floods is analysed by calculating the shape coefficient. The analysis of the main five river systems in Guangzhou shows that their branch proportions are high and dose. The geomorphological conditions for storing and chaimelling water in the area are quite good, but the floods are fairly frequent. According to the geomorphological characteristics, four regions are delimitated and evaluated for water conservancy construction. Relevant engineering measures of water conservancy are also suggested.更多还原
