从港口到卫所——澉浦镇平面格局的变迁

From the Harbor to the Weisuo——A Morphological Research of Ganpu town

澉浦镇在南宋至元代是典型的港口贸易市镇,彼时其城市核"镇市"是沿通港运河及其支河延展的带状街区。明初,以"镇市"为基础改建的澉浦守御千户所沿用了前代的路网系统,但却破坏了原有的水系形态,以致该镇丧失优势交通区位,区域经济重心外移。澉浦镇平面格局的中长尺度历史变迁呈现了该镇由盛而衰的生命周期。这一变迁的内因在于当地结构单一的滨海型经济对海洋政策极为敏感,宋元明海洋政策的更迭、澉浦港的兴废密切牵动着市镇的起落。

As a typical port town in the Southern Song and Yuan Dynasties, Ganpu has a central urban district alongside the canal(and its branch channel) which leads to the port. In the early Ming Dynasty, the Weisuo, which were built on the old urban district, adapted the previous road network, while destroyed the original river system, so that the town lost its advantageous traffic location and the center of the regional economy was shifted outside. Its long-term morphology indicates the whole life cycle of this town. The internal cause of its changes is that the local coastal economy with a single structure is quite sensitive to Marine policies, hence the different Marine policies conducted by Song, Yuan, and Ming as well as the openness of port did impact the survival condition of the town.
