    研究認為： （ 1 ）黃河河口口門逕流潮汐區域並非持續保持淤積狀態，在特定的來水來沙、邊界條件和海洋動力條件下，該區域可以處于沖刷狀態； （ 2 ）從河口泥沙沉積分配的過程來看：三角洲與濱海區泥沙的沉積變化趨勢是基本一致的，各部位的泥沙沉積比例變化基本呈波動狀態，且三角洲與濱海區泥沙的沉積比例與來沙量密切相關，基本成正比關系； （ 3 ）在口門處，影響泥沙沉淤的因素主要集中在潮汐頂托、口門逐漸加寬、河口門分汊、鹽水造成絮凝等，本報告主要對口門加寬，口門西妥理工大學工程碩士專業學位論文分漢對河道淤積的影響進行了定量分析: （一扣根據實測資料首次建立了河贖流路泥沙沉積分配的回歸計算式，據此可以預估計算河口不同區域泥沙的沉淤量; 、 5 ）本項研究首次論證了河口三角洲岸線動態平衡的概念，並建立了黃河河口來沙量與造陸面積的相關關系，得出了當河口多年平均來沙量維持在3 . 45億t時其河口三角洲岸線則可能處于動態平衡狀態的重要結論; 『 6 ）本項研究首次提出了河口泥沙優化調控的概念，並對其宏觀優化調控模式進行了初步探討。

    中古華北之所以仍能保持良好的水環境，並非由於彼時降水遠比後代豐富，而是因為山區森林植被仍然良好，具有較強的水源涵蓄能力；黃土高原水土流失不甚嚴重，黃河決溢移徙較少、危害較輕，湖泊沼澤尚未因泥沙淤填而致大量消亡，可以瀦積巨量的水源。

Based on the topographic features and data of sediment particle size of bed load at the fluctuating backwater reach of liujiaxia reservoir, the streamwise variation and variation process of median diameter of bed load during silting and scouring periods of the fluctuating backwater reach are analyzed, and it can be seen that the turning point for the sediment diameter variation from coarse to fine is located at the outlet of shigou gorge of the fluctuating backwater reach

    摘要根據劉家峽水庫變動回水區的河段地形特徵和歷年河床質泥沙粒徑級配資料，分析了變動回水區河段淤積和沖刷時，河床質泥沙中值粒徑的沿程變化和歷年河床質泥沙中值粒徑變化過程，並指出粒徑分佈由粗變細的轉折點在變動回水區寺溝峽峽口處。
  5. The analyzed results are as follows : the late 1960 ' s cutoff of riverbends increased both the runoff amount and the sediment transport amount of the lower reach of jingjiang river, while the sediment deposition decreased in the lkngting lake area ; after the mid 1980 ' s, both the middle reach of yangtze river main stem and the dongting lake occurred a trend of decreasing annual sediment transport as a result of decreasing sediment releasing from the upper reach of yangtze river ; and in the recent 3 years ( 2003 - 2006 ), the three gorges reservoir first impoundment additionally reduced the sediment concentration in the middle reach of yangtze river flow with a long time, so a distance would be quite long for suspended sediment recovery, but the distance for bed - material load of suspended sediment recovery would be quite short

    分析結果表明： 20世紀60年代下荊江裁彎后，三口（松滋口、太平口、藕池口）分流分沙減少，下荊江徑流量和輸沙量相應增加，洞庭湖泥沙淤積減少； 80年代中期以後，長江中游幹流及洞庭湖出口的年輸沙量呈減少趨勢，城陵磯至武漢河段河床由淤積轉為趨向沖淤平衡；三峽工程初期蓄水運用后，長江中游含沙量沿程恢復距離較長，但床沙質部分恢復距離相對較短。
