分析了不同历史海图采用的不同深度基准面的关系，利用GIS，建立了长江口和杭州湾的DEM，作为演化分析和通量计算的参考。在一个世纪左右时间尺度的大面积沉积分析的基础上，结合泥沙动力学和沉积方法，建立了长江口泥沙收支模型。根据这些结果，得出了长江口一些重要断面的泥沙通量。河口进行了计算。
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.
