| 摘 要： | 河道采砂可对河道的稳定性、航运安全、生态环境等造成重要影响。河道采砂可能会增加河流的输沙,也可能会减少河流的输沙。长江中下游河道的采砂量虽然很大,但却不是导致入海泥沙减少的主要原因,由河道采砂引起的河流输沙减少的相应比例应该不到采砂量的10%。汉口站和湖口站的来沙减少是造成大通站输沙减少的最主要原因。 |
| 关 键 词： | 河道采砂 输沙 长江 |

| Abstract: | Instream sand mining in river channel can bring significant influence on stability ofriver channel and bank,shipping safety,ecological environment.Instream sand mining can increase or decrease of the river sediment discharge.Though large quantity of sand is extracted in the recent years,but it is not the main cause of the decrease of sediment discharge of Yangtze River to the sea.The contribution of instream sand mining to the decrease is not more than 10% to the amount of the sand which has been drawn out. |
| Keywords: | instream sand mining sediment discharge the Yangtze River |
