为了分析长江干流武汉至安庆河段建设“黄金水道”的可行性，采用资料分析、数学模型计算等手段，研究了长江上游溪洛渡、向家坝、三峡等11座水库联合运用后，该河段河道冲淤演变与航道条件变化趋势。研究成果表明，上游建库后，该河段总体河势仍将保持基本稳定，但局部河段可能会发生调整；上游建库对航道条件的影响总体上利大于弊，有利方面为枯水期的补水和航槽的冲刷，不利方面包括心滩和边滩冲刷可能引起的航槽不稳、碍航浅滩在蓄水期冲刷不充分、局部河段河势调整等变化。

In order to analyze the possibility of building "golden waterway" in the river reach from Wuhan to Anqing in Yan-gtze River, by the methods of data analysis and mathematical model calculation, the river channel evolution and navigation chan-nel condition variation trend in this reach after the co-operation of 11 reservoirs in the upstream of Yangtze River, such as Xilu-odu, Xiangjiaba, and the Three Gorges reservoir, were analyzed. The research results show that after the operation of the up-stream reservoirs, the overall river regime remains stable with local river regime changes. The beneficial influence of the upstream reservoirs is more than harmful influence. The beneficial aspects are the discharge increase in dry season and erosion of naviga-tion channel by sediment decreasing. The harmful aspects are that the unstable channel caused by erosion of point bar and chan-nel bar, insufficient erosion of shoal in storage period, adjustment of local river regime, etc.
