| 摘 要： | 揭示了曹娥江出口江道演变的影响因子:既有自然的,也有人为的,主要包括地转偏向力、径流量、来沙量和人类活动等.认为曹娥江出口江道的频繁摆动在很大程度上受制于钱塘江主槽的变迁和南股槽的变化.从兼顾防洪排涝和两岸围涂造地考虑,曹娥江出口江道以出东北方案为佳.提出了"因势利导,围涂治江"的整治原则.堵截南股槽可以稳定钱塘江主槽走向,进而稳定曹娥江出东北的走向,同时也可增加围涂面积.

| Abstract: | The factors offecting the water outlet evolvement of Cao'e River are set forth:there are some nature and artificial factors of water outlet evolvement of Cao'e River, including mainly the deflection force of earth rotation, the runoff volume, the sediment volume, the human activities and such like.The water outlet of Cao'e River swings frequently, which is controlled to a great extent by the change of Qiantang River's main channel and its south channel. On the condition of flood control and reclamation of the tidal flats along two banks, the optimum alignment of the water outlet of Cao'e River is northeast. The dredging principle is put forward "to guide it along its course of development and bring the river under control by means of reclamation of the tidal flats". Blocking the south channel can stabilize the alignment of Qiantang River's main channel and the River to the northeastwards, which at same time can enlarge the reclamation area of the tidal flats. |
