【摘要】 系统分析康定龙头沟温泉逸出气CO₂的百分含量异常与该区域中强地震的对应关系。发现龙头沟温泉CO₂的百分含量成组异常（3个月时间内出现多次突降,N≥2次）,在该区域中强地震的中短期预报中比单次异常更为可靠,可以在日常地震分析预报中加以运用。更多还原

【Abstract】 In this paper,through a systematic analysis of the relativity between percentage content anomaly of the escaping CO₂ from the hot spring at Kangding Longtougou and the moderate strong earthquake in the region,it is found that the group anomalies of CO₂ percentage content of hot sprint in Longtuogou（within three months if there is multiple dump,N≥2 times） is more reliable than a single anomaly for the short-term forecasting of strong earthquake in the region.This result can be applied in the routine earthquake analysis and prediction.更多还原
