摘　　要：宁蒗-盐源地区地震灾害频发,近50年间就发生10次5级以上地震。2022年1月2日宁蒗5.5级地震造成大量村镇房屋受损。文中首先将此次地震与2012年宁蒗5.7级地震进行对比,结合5.7级地震灾后恢复重建,对震中永宁地区房屋建筑结构进行介绍,然后依据震灾现场收集到的震害资料,对各类房屋建筑,包括当地藏传佛教寺院部分建筑的震害进行总结,最后在简要分析房屋震害特征的基础上,结合震后恢复重建工作,对进一步提升当地村镇房屋抗震防灾减灾能力、保护民族传统建筑和宗教特色建筑提出建议。Earthquake disasters frequently occurred in the Ninglang Yanyuan area,and ten earthquakes with M_(s)≥5.0 occurred in the past 50 years.On January 2,2022,the 5.5 magnitude earthquake hit Ninglang County,which caused seismic damage to a large number of rural buildings.In this paper,firstly,this earthquake is compared with the Ninglang M_(s)5.7 earthquake in 2012.The building structure in the Yongning area of the epicenter is combined with the post-disaster recovery and reconstruction of the M_(s)5.7 earthquake.Then,according to the seismic damage investigation data collected at the earthquake disaster site,the seismic damage to all rural buildings,including local Tibetan Buddhist temples,is summarized.Finally,based on a brief analysis of the seismic damage characteristics of houses,this paper puts forward some suggestions for further improving the anti-seismic disaster prevention and mitigation capacity of local rural buildings and protecting traditional national and religious buildings in post-earthquake recovery and reconstruction work.
