龙滩水库2006年10月蓄水以来，库区地震活动频繁，这可能是原有构造地震的进一步活动，也可能是水库诱发地震。因此，有必要对龙滩水库蓄水后发生的地震性质进行判断。本文根据国内外已发生水库诱发地震震例资料和以往经验，结合龙滩库区具体情况，利用定性判断法和概率统计法对龙滩库区地震性质进行验证和判断，结果认为：龙滩库区蓄水后发生的地震属诱发地震。

After Longtan Reservoir retained water, seismic activities became frequent in the reservoir area.  It may be further activities of the tectonic earthquake, or it may be inducedearthquake by reservoir.  It is necessary to analyze the nature of earthquake. In this paper, basing on domestic and abroad reservoirinduced earthquake information and past experience, and combined with the specific circumstances, the nature of earthquakes in Longtan Reservoir area were verified as reservoirinduced earthquake.
