循水造形——雨洪韧性城市设计研究

摘要

Due to global climate change,extreme weathers have brought about more floods to cities.The paper introduces a new urban design approach that improves the resilience of cities against flood by shaping urban morphology and spatial environment.The paper discusses the concept of resilient urban design for flood control,establishes a theoretical framework.By four focus issues,the paper analyzes improvement measures of resilient flood control from land use optimization,city structure organization,multi-use space creation,and systematic integration.Resilient urban design for flood control is an extension of traditional urban design,and offers new possibilities of eco-city performance improvement.%全球气候变化导致极端天气出现的频率和强度骤增,城市雨洪灾害日益严重.通过城市形态和空间环境塑造的手段来提升城市雨洪韧性的城市设计方法打破了传统的设计模式,成为应对城市雨洪灾害的有效途径.文章首先基于韧性城市的相关理论探讨了雨洪韧性城市设计的概念和内涵,建构雨洪韧性城市设计的理论框架;其次,结合设计案例,围绕四个城市设计的核心问题,分析设计实践中提升城市雨洪韧性的方法,包括土地利用优化、城市结构组织、多用空间塑造和城市系统整合;最后,对实际应用中面临的挑战做了进一步思考.雨洪韧性城市设计拓展了传统城市设计的外延,为生态城市的性能化设计提供了新的可能.
