摘要
本文通过模型试验研究和实测资料的分析．着重对山区河流干支流（特别是长江与嘉陵江相汇）汇流后的特性进行了深入的研究．结果表明：干支流的汇流比｛Ｑ／Ｑ｝是影响交汇角大小、汇流面坡降、输沙率变化等的主要因素，同时，利用汇流比Ｑ／Ｑ这一特征值，建立了它与汇合口的水力和泥沙运动变化的部份相关关系，从而揭示了山区河流干支流相汇后的变化特性．
Based on the model test and the field data analysis,the paper emphahcally reserches on the convergence charactristics (the main stream and the tributary stream)in mountain area.The result showes that the convergrnce ratio(Q/Q)is a key factor which affects the convergence angle,slope changes,sediment transport and so on.The paper,also,argues some facial relations between Q,./Q and the flowand sediment transport.
