摘要
本文通过四川壤塘藏族地区寺庙庙谱、藏文手稿、文献档案、访问材料和现场调查等资料的发掘、考证和分析研究，确认１４４３年（明英宗正统８年，藏历第七绕迥阴水猪年）在今壤塘县中壤塘地区，１７９０年（清乾隆５５年，藏历第十三绕迥阳金狗年）在今壤塘县热窝──达格一带，各发生一次破坏性地震。经过实地考察和核证，结合壤塘地区现今破坏性地震研究，并考虑到该地的地形地貌条件、建筑物的结构特点和质量等进行地震学分析，对两次地震的参数进行了评定。壤塘县１４４３年和１７９０年两次地震史料的发掘和参数的确定，填补了壤塘地区历史地震的空白，为国家南水北调西线工程在大渡河上游的地震安全性评估和地震预报、防震减灾等研究提供了重要的地震资料依据。
Based on exploring,examing and correcting,analysing and studing the temple trees,the manuscripts in Tibetan, the documents and archives ad the visting data as well as investigation on the spot,It has been determined that the two destructive earthquakes occurred in central Rangtang region,Rangtang county in 1443 and in Rewo -Dage region,Rangtang county in 1790 respectively. Combined with present research on destructive earthquakes in Rangtang region and taking topographic and geomorphologic conditions,structure features and mass of buildings into account,the authors,through field investigation and check, made a seismological analysis and evaluated the parameters of the two events.Exploring the historical data and determing the parameters of the two events in Rangtang county In 1443 and 1790 filled a gap of historical earthquakes in Rangtang region and provided importamt basis of seismic data for some researches, including safety evaluation in upper reaches of Dadu He of west part engineering under national project carrying water to north from south, earthquake prediction and earthquake preparedness for disaster reduction.
