northeast faults control the spread of the anhui riverway, and eastwest faults resulted in the widening of the river and the occurrence of nodes, then the stream raised and the riverway turn into goose pattern braided river . northwest faults and northsouth faults influence the evolvement of partial riverway, for example, the northwest lujiang-zhongming fault influence the evolvement of tongning shoals, and the northsouth faults passing through zongyang-digang make the riverway's direction from north-east to north-south 北東向斷裂構(gòu)造控制了皖江河型的展布;東西向斷裂構(gòu)造影響河道的拓寬,形成磯頭,磯頭挑流進(jìn)一步使河道形成穩(wěn)定的鵝頭型;北西、南北向斷裂影響局部河道的發(fā)育演變,如北西向廬江-鐘鳴斷裂影響銅陵沙洲的發(fā)育演變,南北向斷裂影響樅陽(yáng)、銅陵、獲港河道使其延伸方向由北東轉(zhuǎn)向南北向。
