摘要
城市日益成为复杂的巨型系统,同时也越来越脆弱,韧性理论为之提供了新的思路。韧性概念有"能力恢复说"、"扰动说"、"系统说"和"提升能力说"四种典型定义,这一概念不关注城市系统是否恢复灾前状态,它强调的是"重组"能力,包括吸收外界扰动、学习和再组织、快速恢复正常和软硬件应对能力。确定韧性城市指标需要遵循符合韧性意涵、能比较、代表性和可行性四项原则,这一评估指标包含气候灾害韧性、经济韧性、社区韧性、组织韧性和基础设施韧性等层面,国际韧性城市实践主要有自上而下、自下而上及二者混合推进类型。尽管韧性评估指标存在获取实证数据困难、稳定不变假设和无形韧性难以量化等局限,但毋庸置疑,它为推动城市风险治理提供了新政策和重要的行动指南。
