摘　　要：地貌环境与城市化相互关系是城市自然地理学研究的核心,从城市地貌学角度分析了上海城市地貌特点和地貌形变过程,探讨了城市地貌形变与城市生态环境之间的关系,特别是城市地貌形变引起的一系列生态环境效应,如城市防汛压力增大、地面积水愈加严重、城市河流淤积加厚、城市植被生境趋于单一等。在此基础上提出了三大应对策略:(1)在黄浦江下游河口尽早修建挡潮闸;(2)沿黄浦江、苏州河修建生态防汛墙;(3)及时进行城市规划调整,在再城市化过程中合理规划城市水面率和城市蓝线宽度,依据地貌形变的强弱来增加负地形(河流、湖泊)的比例,使已经损失的地面标高得到一定的补偿。上海只有充分重视城市地貌特点才能走上安全、健康、持续的城市发展道路。The relationship between geomorphology and urbanization is the core of the urban physical geography.From the perspective of urban geomorphology,this paper analyzed the urban landforms and the land deformation process(LDP) of Shanghai,discussed the relationship between LDP and urban eco-environment,especially a series of eco-environmental effects caused by the LDP such as the increasing pressure in controlling urban flood,the more serious surface water accumulation,the thicker sediment of urban river and the single living environment of urban vegetation.This paper proposes the following three recommendations.(1) The tidal gate in Huangpu River Estuary should be constructed as soon as possible.(2) Building ecology flood control wall is necessary along the Huangpu River and Suzhou Creek.(3) The urban planning should be adjusted timely.The urban water rate and blue line width should be planned rationally.The proportion of the negative terrain(rivers,lakes) should be increased in the process of re-urbanization to compensate the elevation loss in some degree.Shanghai must fully consider the urban landforms.Only in this way can Shanghai take a safe,healthy and sustainable urban development.
