摘要
基于河流熵概念，探讨了冲积河流系统自我调节机制及河流能量分配耗散特点。以变分原理为基础，推求了河流系统能量耗散规律；结合水利工程对河流的干扰，研究分析了河床调整自由度与河流能量分配、耗散间的制约关系。
This paper introducted the concept of river entropy. Based on the trending law of river system the self-adjusting mechanism and energy dissipating properties of alluvial river have been analyzed in the view of system. According to the variation principle, the auther inguired the energy dissipating regular pattern of river system and further studied the relation between freedom digree of riverbed adjustment and river energy dissipation to counter the river distrubance by human activities.
