  1. Influences of the shrink of dividing channels and the dongting lake on the flood in the yangzte river

    分流河道淤積與洞庭湖萎縮對長江洪災的影響
  2. Due to issues of dongting lake districts flood composition, the evolution of sediment flow, the river and lake ( r & l ) distribution characteristic as well as the layout of r & l - dredging engineering, the article simulated the model of the dongting lake terrain change by using the gis technology and adopted the limited volumetric method to establish the two - dimensional hydraulics computation model of lake in order to forecast the water level, the flow capacity, the speed of flow and changes of flow field after implemented the project, which have provided the reliable theoretic basis for the decision - making and implementation of renovation for river course, canal and harbor and river course - dredging engineering

    摘要針對洞庭湖區的洪水組成、水流泥沙演變、河道湖泊水系分佈特點以及河道湖泊疏浚工程布局情況，利用gis技術模擬洞庭湖地形變化，採用有限體積法建立了湖泊二維水力學計算模型預測疏浚工程實施后的水位、流量、流速流場變化，為河道、航道港口整治、河道疏浚清淤等工程決策與實施提供了可靠理論依據。
  3. That favorable water environment benefited, not only by the rather large percentage of forest cover with quite strong capacity of water conservation in mountain areas, but also by the comparatively lower gravity of soil erosion in the loess plateau in the middle and lower yellow river basin while numerous lakes and swamps still existed at that time and maintained a huge water storage

    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。
  4. 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。
  5. It proposes that under the drying climate background, the lakes disappeared mainly because that : firstly clay and sand silted up by the yellow river flooding ; secondly human activities generated great effects

    認為在氣候變乾的大背景下，湖泊消失的原因主要有兩個：一是黃河泛濫所造成的小清河流域的泥沙淤積；二是疏浚河道、圍湖造田、過渡利用水資源等人類活動的影響。
  6. But currently a huge amount of sediment deposited there has caused severe problems and need to be dredged. dredging is one of the effective engineering measures to control floods and improve navigation, irrigation conditions and environment

    但是，目前這些河流、湖泊、水庫和港口的泥沙淤積嚴重，需要進行清淤疏浚，以提高防洪、灌溉、通航能力，改善生態環境。
