| 摘 要： | 长江是我国的黄金水道,对长江安徽段河道演变的研究将有助于岸线资源的开发利用、河势变化分析及河道整治。本文运用RS与GIS方法对四期遥感TM影像图,采用目视解译和微机图像处理相结合的方法,分析研究了1980年以来长江干流安徽段河道的时空变化特征和规律。研究表明1980年以来长江干流安徽全河段总体河势保持相对稳定,未发生长河段的主流线大幅度摆动现象,但局部河段的河势仍不断调整,有的河段河势变化还相当剧烈。1980～2000年长江河道多处表现为泥沙的淤积作用,在分汊型河道边缘滩州和江心洲淤长作用明显,2000～2008年河道表现出明显的冲刷状态,主要原因在于上游来沙量的减少和下游的岸滩防护工作有效开展。2000～2008年,河流上段内滩洲冲刷速率大于下段。
