摘要
取一小流域为典型，从系统角度分析了冲积河流系统的基本结构特征及水沙、河流演变特性。同时研究了水电工程对河流水沙条件的影响特点，以及冲积河流系统河流反应的特点、发展趋向性。对一些水库修建后，下游河道的河性、河床形态变化进行了分析，指出了河流系统的良性循环与水电开发建设的可持续发展必须协调起来。
The basic structure and characteristics of river system is expounded by overall analysing a tributary system of Jinghe River. Based on the dissipating principle of river system energy and system adjusting regularity, the river reaction caused by application of hydroelectric projects is studied,analysed the properties and law of fluvial processes at the downstream of reserviors.
