中文摘要：

以铜陵黑沙洲河段为研究对象,用水沙地形资料结合遥感数据分析了该河段的演变特性.首先利用该河段多年水文泥沙和地形等相关资料进行对比分析,并在微观上侧重分析该河段天然洲、黑沙洲的边滩演变和深槽变化及主流摆动,其次以ERDAS软件为平台,通过对已获取的遥感数据进行处理和集成,对演变特性做补充,从宏观上分析铜陵河段的河势演变特点,最后预估了铜陵河段演变趋势.

英文摘要：

Taking the Heishazhou reach as a research object,this paper analyzes main stream＇s sway,the evolution of pool,point bar and shoal in detail;and aims to finding channel conditions in Tianranzhou reach and Heishazhou reach.The data used in this research are drawn from large numbers of long-term natural recorded and measured map,including volume of water and sand and terrains of channels.Based on these,combining river dynamics with multi-dimensional data,supplementary analysis of the evolution features is made.Finally,the key technologies in remote sensing image processing,integration and application are used to make prediction for the evolution tendency of this reach based on ERDAS software.
