1856年黔江-咸丰地震在不同版本的目录中，震级和震中烈度均存在不小的差异。本文通过对1856年黔江-咸丰地震史料的收集，查阅更大范围的史志、地方志，详细分析了史料中此次地震造成的震害情况。对黔江-咸丰地震进行实地考查，并通过对西南山区近年来几次地震的对比分析，从震害角度、地震烈度图不同烈度面积的角度，进一步讨论震中烈度的可能性。采用多种方法对地震震级进行估算。但黔江-咸丰地震的震中烈度和震级确定依然是个难题，还需进行进一步研究。

In different versions of the directory,the 1856 Qianjiang-Xianfeng earthquake shows not a small difference on the epicentral intensity and magnitude. In this study,we gave a further collection of historical materials,consulting a wider range of historical records and local chronicles,and conducting a detailed analysis of the earthquake damage caused by it. Based on the field investigation of the Qianjiang-Xianfeng earthquake and the comparative analysis of several earthquakes in the southwest mountainous area in recent years,the possibility of the epicenter intensity is further discussed from the point of view of earthquake damage and the different intensity areas of seismic intensity map. We used several methods to estimate the magnitude of the earthquake. However,the determination of the epicentral intensity and magnitude of the Qianjiang-Xianfeng earthquake is still a difficult problem and needs further study.
