2008年5月12日发生的汶川7.9级地震是中国自1976年以来破坏性最大的地震。这一事件造成了巨大的破坏和生命损失，暴露了受影响省份在制定和执行建筑管理条例方面的弱点。地震发生后，中国政府开展了大规模的救援和恢复行动。提交人参加了在事件发生后5个月和11个月在受影响地区进行的实地研究，当时恢复工作已经很深入。这项研究的目的是评估地震对建筑环境和社会造成的影响，收集关于正在进行的恢复工作和未来计划的信息，并演示如何使用工具来收集有空间参照的损害和恢复数据。在现有卫星图像的基础上，辅以地面观测，建立了地理数据库，其中载有关于受灾地区若干地区的损害和恢复情况的信息。本文概述了恢复过程，描述了用于构建这些地理数据库的方法，并提供了一些分析所获得的数据。有人认为，这种数据库在管理灾后恢复和建立恢复进程的永久记录方面具有巨大潜力。
The M7.9 Wenchuan earthquake on May 12th, 2008 was the most destructive in China since 1976. The event caused huge damage and loss of life and exposed weaknesses both in the formulation and implementation of the regulations governing building in the affected provinces. Following the earthquake a massive relief and recovery operation was mounted by the Chinese government. The authors took part in field studies in the affected area which took place 5 and 11 months after the event, at which time recovery operations were well-advanced. The aims of the study were to assess the effects caused by the earthquake to the built environment and society, to collect information on the ongoing recovery efforts and future plans, and to demonstrate the use of tools that allow the collection of spatially referenced damage and recovery data. Based on available satellite imagery supplemented by ground observation, geodatabases were constructed containing information on damage and recovery in several parts of the affected area. The paper gives an overview of the recovery process, describes the methods used to construct these geodatabases, and offers some analysis of the data obtained. It is argued that such databases have great potential for the management of post-disaster recovery and for creating a permanent record of the recovery process.
