| 摘 要： | 上海湖沼平原和滨海平原地貌类型划分应遵从地貌特征，为工程应用方便，可划分地貌亚区。地貌分界线上典型的地质剖面，为湖沼平原第一硬土层与滨海平原暗绿色硬土层属于同一地质时代提供了直接证据。由于古河道、台地等古地貌特征，造就了不同地貌及地貌亚区之间地层差异。

| Abstract: | The demarcation of landform type should follow the landform characteristic is put forward.For convenience on engineering application,the landform can be divided into sub areas.The typical geologic sections on the boundary of different landform area and sub areas provide the direct basis that the first hard soil layer in lake-swamp plain and the dark green hard soil layer in sea-shore plain belongs to the same geologic ages.The action of ancient river and mesa etc.,which caused the difference of subsoil laye... |
