【摘要】 在给出黄河生命低限流量和河流生命定义的前提下,以水流连续方程和动力方程为理论基础,得到黄河干流主要节点生命低限流量数值。通过估算入黄一级支流最低入黄流量及黄河干流自然损耗量,如河道水面蒸发、水库水面蒸发、水库渗漏量、河道侧渗量等,逐步得到了黄河干流主要断面生命低限流量数值。该数值是维持黄河健康生命的关键指标之一。更多还原

【Abstract】 The paper obtains the numerical value of low-limit flow at the main nodal points of the Yellow River under the conditions of providing the life low-limit flow of the Yellow River and the definition of river life and taking continuity equation and dynamic equation as theory.It gradually obtains the numerical value of life low-limit flow at the main sections of the Yellow River through rough estimation of the lowest discharge of first grade tributary flowing into the Yellow River and natural loss of the Yellow River,such as channel surface evaporation,reservoir surface evaporation,the quantity of reservoir percolation and the quantity of channel lateral seepage.The numerical value is one of the key indexes for keeping the healthy life of the Yellow River.更多还原
