| 摘 要： | 将历史海图的基准面进行统一换算，采用GIS技术，实现了长江口及杭州湾DEM，作为长江口及杭州湾冲淤分析及通量计算的基础。通过百年时间尺度的大范围冲淤分析，结合泥沙动力学、沉积学方法，建立了长江口泥沙收支平衡模式，以此为基础，计算了长江河口若干重要界面的泥沙通量。 |
| 关 键 词： | 长江口 泥沙冲淤 计算 通量 |

| Abstract: | The paper analyzed the relationships of different Depth Datum Levels adopted in different historical nautical charts. By using GIS, DEMs of Changjiang Estuary and Hangzhou Bay were founded as the references of evolution analyses and flux calculations. Based on the great area deposition analyses in the time scale of about a century, combining sediment dynamics and sedimentation method, the paper set up the mode of sediment budget of Changjiang Estuary. According to these results, sediment fluxes for some important cross sections in Changjiang Estuary were calculated. |
