中心城区“向地下要空间”的城市遗产保护策略——以徐州市为例

The Urban Heritage Protection Strategy of Seeking Space from Underground in Central City——Taking Xuzhou City as an Example

在减量发展的新城市战略背景下,城市存量更新使得城市地面空间不足与城市空间需求之间的矛盾在城市中心区域尤为突显,其中城市遗产保护已经是城市存量更新中不可回避的问题。国内外城市在“向地下要空间”中保护文化遗产主要应用了“构建历史街区地下空间网络”、“加强轨道交通周边城市遗产保护”、“原址展示地下城市遗产”以及“提升城市遗产地下空间环境品质”四种策略。为解决徐州市中心城区老旧历史地段普遍存在的城市功能缺失以及历史环境破坏问题,应用这四种策略通过地上地下一体化设计、原址展示和加强地下景观设计等方法促进徐州市城市遗产保护和发展。

With the new urban strategy of reduced development,the contradiction between urban land space shortage and urban space demand is particularly prominent in the central district of city due to built-up area redevelopment.The protection of urban heritage has become an unavoidable problem in built-up area redevelopment.In the exhibition and preservation of urban heritage,domestic and foreign cities mainly apply four strategies to protect cultural heritage in the process of seeking underground space:“building the underground space network of historical blocks”,“strengthening the protection of urban heritage around rail transit”,“displaying underground relics in situ”,and“improving the environmental quality of urban heritage underground space”.To address the lack of urban functions and the destruction of historical environment that commonly existed in the old historical areas of the central district of Xuzhou,these four implementation suggestions are applied to promote the protection and development of urban heritage in Xuzhou through the integrated design of ground and underground,the original site display,and the strengthening of underground landscape design.
