    摘要:以武汉新区四新地区概念规划与核心区城市设计优胜方案为案例,对正统物质规划中的“非水既土,非土既水”的刚性水地关系提出挑战。从分析现有问题入手,通过引入荷兰圩田缓冲系统,利用多样化规划手段、产业结构群、土地利用模式来重构一种新型的、基于多样选择的、可适应性的水地关系。所提倡的自适应性设计方法论将一部分水地界面形态交给圩田缓冲系统去自适应性地生成,而非由规划师一锤定音式地按单一形式预先在规划图纸上完全界定。这种设计新思维引入自适应性作为设计手段之一来防止人类正统物质性规划方法对现存自然生态系统的同化与破坏。进而重构“人—水—地”之间的可持续发展关系,使人、城市空间、景观与自然生态系统协调发展,共同演进。

    Abstract:This paper takes the winning proposal of conceptual planning and urban design for Sixin area in Wuhan New District as a case to launch a challenge to orthodox physical planning method which mostly employs a rigid relationship between land and water as "either land or water". The winning proposal started from the analysis on existing problems. It has proposed a new land-water relationship based on diversity and self-adaptive mechanism by using buffering system of Dutch polders, diversified means of planning, diversified clusters of industries, and diversified mode of land use. The proposed self-adaptive methodology leaves the generating of typologies of the interfaces between water and land through buffering polder system, instead of giving the decisive word through urban planners on planning drawings in advance. The new design thinking has introduced adaptation as one of the design means to prevent existing eco-system from destruction and homogeneity caused by rigid physical planning. It has reconstructed a sustainable relationship among human, urban space, landscape and natural system towards mutual evolution.
