论"稳定主槽、调水调沙"的治河方略

随着人们对黄河泥沙输移规律认识的不断深入，治黄方略或主张也在不断地更新。微弯整治基于多年游荡河道的防洪抢险经验，其能达到减小游荡范围的治理目标，但主槽没有稳定；双岸整治方案是基于窄深河槽洪水期具有很强的输沙潜力与泄洪能力。小浪底水库投入运用后，必须形成稳定的主槽才能保证防洪的安全，提高河道的输沙能力，从而达到更好的减淤目的；洪水漫滩机会减小了，才能使黄河滩区人民与自然和谐相处。因此，主张束水输沙，认为“稳定主槽、调水调沙”的治河方略符合当今黄河的实际。

On General Plan of River Harnessing of "Stabilizing Main Channel and Regulating Water and Sediment"

Along with deeper understanding on the rules of transport of sediment of the Yellow River,the general plan for the Yellow River harnessing or proposition is also updated continuously.Mini-bend training,which is flood control and emergency repair experiences of meandering channel accumulated for years,can achieve the objective of reducing meandering scope but can not stabilize the main channel.Banks training is conducted based on narrow and deep channel in flood season that has strong potentiality of sediment transport and flood carrying capacity.After putting the Xiaolangdi Reservoir into operation,it can guarantee the security of flood control,increase the sediment transporting capacity of the channel and better achieve the aim of sediment reduction only as a stable main channel is formed.The people living on the floodplain area can get on well with the nature only there are few chances for flooding.Thus,it favors for narrowing the channel for sediment transport and considers that the general plan for river harnessing of "stabilizing main channel and regulating runoff and sediment" tallies with the present actual situation of the Yellow River.
