| 摘 要： | 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。疏－疏水和疏水是根治长江洪患的唯一出路，开辟分洪河道，疏沙淤垸降和蓄水分洪是长江中游共减灾的重要措施。

| Abstract: | Flood disaster in middle Yangtze River has been a serious hidden trouble or danger for the Chinese nation since ancient times. The cause that flood hazards have not been eliminated for hundreds of years is that the time honored strategies do not suit to the cases for flood prevention.In the view of geological environmental analyses on flood disaster formation and from the synthesis of experiences gained in flood fighting during hundreds of years, sluggish draining of flood, silt sedimentation in channel and building dike blindly constitute the main cause of intractable flood for a long time in the middle Yangtze River. Draining away the silt and water is the only way of stamping out flood disaster. Opening up artificial waterways for flood diversion, draining away the silt of channel into the embanked lowlands, and storing the flood water are important engineering measures for the flood prevention and hazard reduction. |
