长江中游洪患自古乃中华民族的心腹大患，数百年来不得治愈的根本原因是没有做到对症下药。从洪患形成的地学环境分析和数百年抗洪经验总结来看，行洪不畅、泥沙淤积和长期以堵为主的抗洪方式是长江中游洪患得不倒根除的主要原因。疏———疏沙和疏水是根治长江洪患的唯一出路，开辟分洪河道，疏沙淤垸（ 堤背放淤、开垸放淤、水沙分离） 和蓄水分洪是长江中游防洪减灾的重要措施
The flood in the middle reaches of the Yangtze River has always been a serious problem for the Chinese nation. The fundamental reason that the disease has not been cured for hundreds of years has not been the right medicine. From the analysis of the geo-environment caused by the floods and the sum of flood-fighting experience for hundreds of years, the main reason for the flood-stricken areas in the middle reaches of the Yangtze River is the flood-fighting, siltation and long-term flood-fighting methods. Diversion --- Scattered-sand and water-repellent are the only ways to cure the floods in the Yangtze River. Flood diversion channels are open up, silt-lapping sedimentation (embankment dredging, sedimentation separation, water and sediment separation) and flood diversion are important measures for flood control and disaster mitigation in the middle reaches of the Yangtze River
