海绵城市系统构建模式

海绵城市是我国城市水问题综合治理的一种新理念。目前科学界和实践部门因各自的专业所限和视角不同,对于海绵城市的本质内涵、构建模式和建设途径还存在诸多不同观点,缺乏统一认识,在一定程度上阻碍了海绵城市研究与实践的深入。本文试从对城市水问题的基本判断出发,分析指出海绵城市的科学内涵,综合提出海绵城市构建的系统模式。该模式从系统思维出发,总结了海绵城市建设的本质内涵、系统诊断、基本途径和耦合平衡,并统合于海绵城市"一片天对一片地"核心思想,突破专业限制,从宏观上提出了涵盖海绵城市全要素全过程的系统科学范式,可为海绵城市研究、规划与建设提供基础理论支撑。

Systematic construction pattern of the sponge city

Sponge city is a new strategy of integrated urban water management in China. Due to differences in perception and limitations of disciplines in academy and practice circles, understanding of the connota-tion, implementation protocols and approaches of the sponge city are divergent, which hinders the research and implementation of the sponge city. Based on the identification of basic urban water-related problems, this study illustrated the scientific connotation of the sponge city,and proposed the protocols of sponge city construction. Through a systematic review, this study proposed three substantial contents, three diagnosis items, three basic approaches and three balance equations of the sponge city. The fundamental philosophy is matching the sky area with the ground area. A systematic formula that covers all elements and all pro-cesses of general sponge city construction is presented. This study may provide the foundation for research, planning and implementation of the sponge city.
