21世纪的城市发展绝不仅仅是经济实力、科学与信息之争,必然是包括生态环境及减灾防灾在内的城市安全度之争。可以说21世纪城市综合防灾减灾能力的高低,将成为全面衡量城市整体功能及其安是针对城市进行的全灾害的管理,它贯穿于灾害管理全过程,集中于灾害风险和承灾体的脆弱性分析并强调多层面、多元化和多学科的参与合作的全面整合的灾害管理模式。本文介绍了综合城市灾害风险管理的必要性、内涵和原则;综合城市灾害风险管理的对策和实施过程;在此基础上探讨了综合城市灾害管理的实施战略和实施途径。

The Urban development in the 21st Century is not only the competition for economic strength, science and information, it surely is the competition for urban security including ecological environment and disaster mitigation and prevention. It can be said that the capacity for preventing and mitigating disasters will become the mark to comprehensively evaluate the whole function and capacity for defending the safety of a city. The new concept recently introduced in disaster management system in the world is called the Integrated Disaster Risk Management (IDRM). This concept has been introduced to mark the last decade as the International Decade for Natural Disaster Reduction incorporating the International Strategy for Disaster Reduction (ISDR) among other related endeavors. Risk management has introduced structured and systematic processes and procedures for examining risk factors involved and for making decisions based on them. This innovative application of the basic methodology of the risk management process presents a fresh approach to understand the nature of disasters, prevent its harmful effects, as well as seek opportunities from their occurrences. It integrates existing knowledge and techniques on risk reduction and response for disaster management. The concept of IDRM is relatively a new one both in theory as well as in practice. The Integrated Urban Disaster Risk Management (IUDRM) has become an important strategy and model in contemporary disaster management. The IUDRM concept is a purposeful viewpoint that addresses holistically and comprehensively the various concerns and gaps in the urban disaster management cycle. In this regard, it necessarily focuses on the underlying causes of disasters, the conditions of disaster risks and vulnerability of the urban areas. It also emphasizes multilevel and multidisciplinary cooperation and collaboration to achieve effective disaster risk reduction and response. It also facilitates broad-based participation in policy and program development in urban disaster reduction and response as they relate with other development concerns, viz. poverty reduction, land use planning, environment protection, and food security. This paper introduces the necessity, basic meaning and principles of the integrated urban disaster risk management and discusses the countermeasures, implementation process and strategies of the integrated urban disaster risk management. The IUDRM concept emphasizes hazard mapping and vulnerability assessment as a fundamental tool for effective decision-making and efficient sharing of disaster information. Thus, the IUDRM concept promotes good decision-making and effective use of limited resources.
