国际滑坡风险评估与管理指南研究综述

A review of international landslide risk assessment and management guidelines

总结了国际主流滑坡风险评估与管理技术指南的进展和现状,综述了滑坡风险管理范畴中包含的理论和技术框架,研究精度和层次,滑坡编录、易发性、危险性和风险分区研究的技术方法;指出了滑坡风险分区成果的误差来源和可靠性验证方法;基于滑坡风险分区的研究成果,提出了土地利用规划中风险控制措施的建议。总结了主流国家和地区滑坡风险管理的发展历程和经验,结合中国地质灾害防灾减灾的现状,强调了出版滑坡风险评估与管理指南的紧迫性,并展望了滑坡等突发地质灾害风险评估与管理的发展前景。

The international state of the art guidelines of landslide risk assessment and management are reviewed. Some issues in landslide risk assessment study including theoretical and technical framework, study levels and precision, zoning methodologies for landslide inventory, susceptibility, hazard and risk are summarized. Potential error sources of landslide risk zoning results and reliability validating methods are indicated. Suggestion of risk control measures for land use planning is provided based on landslide risk zoning results. History and experience of landslide risk management in main countries and regions are summed up; consequently according to current situation of Chinese geohazard prevention and reduction, the urgency of developing landslide risk assessment and management guideline is emphasized. The risk assessment and management prospect of sudden geohazard including landslide and so on are predicted.
