70年代以来，黄河入海水通量明显下降，本文根据黄河流域的降水、实测径流、“天然”径流、引水量和流域治理措施面积等资料，分析了黄河入海水通量下降的原因，研究了黄河流域水通量与降水变化和人类活动的关系。不同的水源地。不同径流源区降水量的变化对流域水通量的影响不同，引江调水形成“横向分支水循环系统”，流量急剧增加，导致流域水通量显著下降。建立了一个多元回归方程，估算了降水、引水和侵蚀控制措施变化引起的入海水通量变化。
Since the 1970s, the water fluxes from the Yellow River into the sea have declined significantly The formative cause for this is dealt with in this study Based on the data of precipitation, measured and "natural" runoff, water diversion and the areas of erosion control measures over the drainage,the relationship between the water fluxes and the influence of changing precipitation and human activities are studied The Yellow River basin can be divided into some different water source areas. The change in precipitation over different runoff source areas has different effect on the water flux The water diversion from the river forms a "lateral branch water cycle system",which increased intensively and resulted in significant decline in the water flux Since the 1960s, the erosion control measures have been practiced over the drainage basin, leading to a decrease in the water flux into the sea A multiple regression equation is established for estimating the change in water fluxes caused by the changes in precipitation, water diversion and erosion control measures
