摘要
根据实测河道测图资料及水沙资料 ,首次利用断面地形法和输沙平衡法较全面系统地计算分析了长江中下游河道泥沙的冲淤变化及其分布规律 ,计算结果表明宜昌～大通段呈冲槽、淤滩、淤汊特征 ;同时剖析和验证了长江中下游河床具有较强的自动调整作用。
According to channel topographic and water sediment data, using methods of cross section survey and sediment balance, the changes and distribution law of channel scouring and silting in midstream and downstream reaches of Changjiang River are systematically studied in this paper. The results improve that main channel was scoured and flood plain and river branch were silted. And the strong capability of channel self adjusting in Mid and Down stream reaches of Changjiang River is analyzed and proved.
