淤积

Soil erosion is one of the most important ecological environment problems in our country, which results in land resource destroy, soil degradation, land productivity decrease, water pollution, river and water storage works aggradation, flood, avalanche, mudrock flow and menace to the life and wealth of people, and so on.

土壤侵蚀问题是目前我国面临的主要生态环境问题之一，严重的水土流失不仅破坏土地资源、降低土壤肥力、制约粮食生产增长，还污染水环境、淤积河道和蓄水工程，导致洪水、崩塌和泥石流等灾害频繁发生、威胁人民的生命财产等。

And it has given the effects of the all factors on the runoff by 1D river networks mathematical model. Due to the natural and artificial influences, the water-sediment transport has greatly changed. It is characterized by marked decrease in runoff and sediment diverted from these outfalls and increase in water-sediment transport of main stream. The key factors causing these changes are aggradation of the three outfalls channels and Jingjiang river cutoff work.

结果表明，受自然因素和人为因素的影响，荆江－洞庭湖江湖水沙输移有了较大调整变化，主要表现为三口分流分沙大幅度减小，干流水沙输移增加；江湖关系变化的主要因素是三口分流道的淤积萎缩和荆江裁弯。

在潮汐河口支流口门上建闸，其闸下淤积面貌主要取决于干流主槽的位置，这与在潮汐河口干流上建闸的闸下淤积问题有着本质上的差异。

The amount and range of sedimentation in the estuary are reduced and the position of maximum sediment thickness point is extended to seawards about 230m.

研究结果认为设置导堤后泥沙在口门附近的淤积范围和数量减少，淤积厚度最大点的位置向外海推进了230m，有利于把河口泥沙输送到深海，效果明显。

The tidal flat along Bohai Gulf extends from Haihe River Mouth to Dakou River. According to the results of field survey, the inter-tidal flat has obvious zonation. From the shore seawards, 4 zones can be identified, and they are depression polygon, inner depositional, erosional and outer depositional zones, and the associated sediment types are mud and clayey mud, mud, alternating laminae of silt and mud, and coarse silt, respectively.

渤海湾潮滩海岸从海河口以南到黄河三角洲北缘的大口河以北，据野外调查发现，这里的潮间浅滩具有明显的分带性，从岸向海可以分为四带，即龟裂带、内淤积带、滩面冲刷带、外淤积带，相应各带的沉积物为：淤泥与粘土质淤泥、淤泥、粉砂与淤泥互层、粗粉砂。

According to statistics after the foundation of the PRC, each year the yellow river takes away from the loess plateau 1.6 billion tons of sand, of which 3/4 silts at the sea port and the rest of which silts in the riverways of the lower reach.
