中文摘要：
丹东市是因港而形成和发展的城市,文章收集了不同时期鸭绿江影响航运的水文特性,探讨影响港口布局进而影响丹东市条带状空间格局的内在驱动力。结果表明：城区空间格局演变是不同时期对水文要素的响应：早期的选址是作为鸭绿江防区薄弱环节来设防,此处的鸭绿江水流平缓、沙洲较多、易于涉水;丹东设制和开埠时期,以鸭绿江的对外港口运输,适宜的潮差和流量是丹东城市雏形的重要因素;随着建设东北东部现代化港口城市的定位,原有丹东内港的水深、潮差、河床宽度和泥沙淤积等要求已不能满足这种要求,城市空间形态沿鸭绿江向大东港方向延伸,形成了丹东与东港同城化的极为狭长的条带状城区。
英文摘要：
Dandong is a city whose formation and development relied on the harbor.Through collecting the materials of hydrological characteristics of Yalu River during different periods,the article discussed on the inner driving force of the influence on the harbor distribution and the banded urban spatial pattern of Dandong by the harbors.The result stated that the evolution of urban spatial pattern is the response to hydrological characteristics in different periods.As the weak defense location of Yalu River is considered most on the earlier city site of Dandong.On the site,the water flow was gentle,the sand bars were more,and it was easy to pass through.On the period of setting city and harbors,optimal tidal range and water flow is the important factor of earlier urban morphology.With the city orientation as the modern harbor city in the eastern part of Northeast China,the characteristics of original water depth,tidal range,river-bed width and sand sediment cannot supply the demand,so the urban spatial pattern of Dandong extends to Dadong Harbor to form the very narrow banded urban area.
