本文运用阿坝州丰富的历史地震资料进行分析研究，结合目前国内历史地震研究的新动向，在阿坝州历史地震资料的基础上，提出了阿坝州历史地震烈度评定表，提出历史地震烈度评定的标志，Ⅲ－Ｖ度，主要根据人对地震的感觉程度评定；Ⅵ－Ｘ度，主要根据房屋、结构物的破坏程度及人员伤亡，地表破坏程度等评定，并按阿坝州历史地震史料记载内容，结合《新的中国地震烈度表》和目前多数人所采用的烈度评定标志，对州内历史地震记载中对建筑物的破坏情况和数量词的运用等进行定量划分等作了统一规定。在此基础上编制出《阿坝州历史地震烈度评定表》，作为对阿坝州历史地震烈度评定时的参考。在历史地震震级的估算中，利用阿坝州历史地震无破坏记载的多，有感点记载详细（到现在的乡、村）等优势。选用现代有仪器记录的州内４－５级地震资料进行统计计算，推算出震级与震感距离的关系式（１），Ｍ＝１．５２ｌｏｇＲ＋１．９；震级与震感距离和烈度的关系式（２），Ｍ＝０．８ｌｏｇＲ＋０．４５Ｉ＿０＋０．７１，其中（１）式的相关系数ｒ为０．９７，标准误差Ｓ为０．２８；（２）式的相关系数为０．９６，标准误差Ｓ为０．２１。并规定了在对历史地震震级计算时应基本满足下列条件时方能进行计算。（１）?
Based on the historical seismic data in Aba, combined with the abundant historical seismic data in Aba, this paper analyzes and studies the historical seismic data in Aba, and puts forward the evaluation table of the historical seismic intensity in Aba Prefecture and puts forward the sign of the historical seismic intensity assessment , Ⅲ-V degrees, mainly based on people's perception of the extent of the earthquake; Ⅵ-X degrees, mainly based on the destruction of houses, structures and casualties, the extent of damage to the surface and so on. According to historical records of Aba Prefecture, Combined with the “New China Earthquake Intensity Table” and the intensity assessment sign adopted by most of the people at present, unified provisions have been made on the quantitative classification of the destruction of buildings and the use of quantifiers in historical seismic records in the state. On this basis, “Aba history seismic intensity assessment table” was compiled as a reference when assessing the seismic intensity of Aba history. In the estimation of the magnitude of the historical earthquake, the historical records of Aba Prefecture were used without any damage, and the detailed records (up to now, townships and villages) were recorded. Using modern state-recorded MS 4-5 earthquakes for statistical calculation, the relationship between earthquake magnitude and seismic distance is calculated (1), M = 1.52logR + 1.9. The relationship between magnitude and seismic distance and intensity ), M = 0.8logR + 0.45I_0 + 0.71, where (1) the correlation coefficient r is 0.97, the standard error S is 0.28; (2) the correlation coefficient is 0.96, the standard error S is 0.21. It also stipulates that when the historical earthquake magnitude calculation should basically meet the following conditions can only be calculated. (1)?
