"宽河固堤,窄河弱防"治理黄河下游宽河道

对黄河下游宽河道现状进行了分析，认为：应采取“宽河固堤，窄河弱防，整治中水河槽”方略治理黄河下游宽河道，在强力推进标准化堤防和完善现有河道整治工程前提下，进一步缩窄河道，修建抵御8000m^3／s流量的滩区堤防；利用模型试验、移动组合式导流坝和超低潜坝技术，探索和进行小水河槽整治，提高滩区安全保障能力和控导工程对于中、小水的约束与控制作用，提高中、小水流的河道输沙能力，构建以堤防和河道整治工程为主体的排洪输沙体系，实现黄河下游河道的长期相对稳定和长治久安。

Harnessing the Wide Channel of the Lower Yellow River by a General Plan of "Consolidating Embankments at Wide Sections and Less Protection at Narrow Sections"

The paper analyzes the present status of wide channel on the lower Yellow River and deems that it should be harnessed by taking a general plan of "consolidating embankments at wide sections, putting less protection works at narrow sections and training normal channel" , further narrow the channel and build dykes in floodplain against 8,000 m3/s under the conditions of energetically carrying forward standardized embankments and improving the existing river training works; explore and conduct small flow channel training, increase the security capacity of floodplains, increase the restraint and control functions of control works in moderate and small flows, build a flood discharge and sediment transport system by taking dykes and river training works as the main and achieve long - tern relative stable of the channel and lasting peace and stability of the lower Yellow River.
