摘　　要：椒江是浙江省的第三大河,上游山溪性河道特征明显、下游潮动力强劲、中游较长河段为洪潮相互顶托作用区,对其最大浑浊带与浮泥运动,极具研究价值。通过分析椒江流域内部分典型工程建设引起的自然条件变化,结合灵江建闸工程初步研究结果,从水流和泥沙角度分析了强潮山溪性河流对工程的水沙响应特征,分析结果可为类似河流工程建设决策及其方案设计提供参考。Jiaojiang River, the third longest river of Zhejiang Province, has significant research value to the maximum turbidity zone and fluid mud movement due to the typical characteristics of mountain streams in the upper reaches, powerful tidal current in the lower reaches, and the mutual uprising effect of flood and tide in the longer middle reaches. By analyzing the changes of natu- ral conditions caused by construction of some typical projects in Jiaojiang River Basin, the paper presents the sediment response of rivers, with strong tidal and mountainous stream features, to the project construction through consideration on the preliminary study of Lingjiang Sluices Project.
