【摘要】 城市可持续减灾是城市可持续发展的基础和底线，本论文旨在通过城市空间在多层次上的评估和设计策略的研究，针对多灾种对城市空间的影响，从灾害发展全过程出发，充分发挥城市空间的能动减灾作用，以实现城市在空间发展过程中融合有意识的减灾理念，构建御灾性城市的目标。在借鉴国内外相关研究成果的基础上，本论文以城市空间作为城市减灾的切入点，综合运用灾害学，生态学，城市设计等多学科理论，通过理论研究和实证分析，试图初步构建起御灾性城市空间体系，并形成系统的可持续减灾评估方法和空间设计策略。本文首先对御灾性城市和减灾的概念进行了系统分析，并立足于城市空间，提出基于可持续减灾的御灾性城市空间设计的概念，核心和特征。其次，从目标的构建及其在城市减灾中的定位、构建基础、多灾种空间应对、多层次空间构成、全过程空间控制以及设计步骤等多个层面系统构建起基于可持续减灾的御灾性城市空间理论体系。再次，从提高环境御灾力以实现灾前长期生态减灾需求和以提高紧急应对灾害能力以实现灾后短期救灾避难需求两个核心层面，对城市灾害评估方法进行总结，并在此基础上从城市整体空间格局和城市细部空间设计两个方面对城市空间在不同灾害发展阶段的减灾设计策略进行了系统研究。最后，论文选取了天津作为实例研究对象，主要采用文献查阅和实地调研相结合的办法，通过对天津城市空间现有问题以及救灾避难需求的分析，系统总结了城市各个空间层次上的减灾设计方法，提出合理的城市空间可持续减灾体系，以构建具有御灾能力的天津城市空间系统。更多还原

【Abstract】 Urban sustainable mitigation is the basis of urban sustainable development. Through the research of multi-level evaluations and design strategies, Urban space aims to give full play to the active role of urban mitigation from the whole disaste process and multi-hazard to construct resilient city with integration of uban space。On the base of research results at home and abroad, Urban space system of, as the starting point of urban mitigation, is constructed through the intergation of disaster science, ecology, urban design theory to built up a space system of resilience city and form the systemic strategies of sustainable mitigation assessment and space design.Firstly, based on the urban space, the concept, core and characteristic of design of resilient urban spatial system based on sustainable mitigation are put forward. Secondly, multi-faceted space mitigation system, including target and position, foundation, multi-hazard space response, multi-level space conposition and design steps is build up to form the theoretical system of resilient city with sustainable mitigation space. Thirdly, two cores are proposed. One is the tactics of long-term ecological disaster reduction with the environment resilence raised. The other is to satisfy the demands of short-term relief refuge with emergency response capability raised. The urban disaster assessment and space design methods are sumed based on the two crucial cores.Tianjin, as a case study, is analyzed space mitigation methods based on the analysis of the existing problems as well as the demands for relief refuge in urban space. The reasonably sustainable mitigation system of urban space is proposed in order to build the Tianjin space system with resilience.更多还原
