黄河水沙过程调控与塑造下游中水河槽

Process Regulation of Runoff and Sediment of the Yellow River and Shaping Normal Channel of the Lower Reaches

随着黄河流域来水来沙过程的大幅变化及人类活动的加剧,黄河的健康状况日趋恶化.通过对黄河健康的内涵、维持黄河健康生命的理论与技术支撑、流域水沙资源优化配置数学模型、大型水利枢纽联合运用对黄河下游河道的减淤作用、塑造黄河下游河道中水河槽等方面的研究,提出了对黄河水沙调控体系的认识,并认为在目前实际的黄河水沙条件下,通过小浪底水库的调节,黄河下游河道经过5～8年的努力,是可以塑造出一个平滩流量为4 000 m3/s左右的中水河槽的.

Along with the variations by a big margin of coming water and sediment and intensification of human activities in the Yellow River basin, the physical conditions of the Yellow River are increasingly worse. The paper puts forward cognition on sediment discharge regulation system of the Yellow River and considers that a normal channel with about 4000 m3/s bankfull discharge could be created through the regulation of the Xiaolangdi Reservoir and 5~8 years effort of the channel on the lower Yellow River under the present actual conditions of sediment discharge of the river, through the studies on aspects of connotation of the river’s health, theory and technical support for keeping the healthy life of the river, mathematical model of sediment water resources optimized configuration of the basin, sediment reduction function on the lower river channel of joint operation of large-scale key water control works and creating a normal channel on the lower Yellow River.
