摘　　要：地震地热前兆的观测与研究是一项具有特色的短临预报新方法,并在地震预报的实践中取得了一定的实效。江苏省地震局在"九五"期间建立了一批数字化地热综合观测台,积累了丰富的观测资料并记录到数个地热异常震例。一年来在边观测边研究的过程中发现数字化地热观测资料具有信息量大、观测精度高、正常动态稳定、异常易于识别、映震灵敏等优点。并对数字地热资料进行了充分的使用和多种方法分析,在研究正常动态特征和影响因素的基础上,总结异常识别和异常分析方法,并通过对典型震例的研究探索地热异常与地震之间的关系。The research on geothermal precursor is a characteristic shortterm prediction method that has a good effect in the earthquake prediction practice.The Seismological Bureau of Jiangsu Province built up a set of digital geothermal synthetical observation stations during 'the Ninth FiveYear Plan', and accumulated plenty of observational data and some earthquake samples of geothem. During research and observation, we found that the digital geothermal data has many virtues such as abundant available information, high precision of observation, stable normal dynamics, easily judged anomaly, sensitive response of earthquake, and so on. Digital geothermal data was well used and multianalyzed in this paper. Based on the study of normalcy characteristics and interferential factors, we summed up some methods in judging and analyzing the anomalies. The relation between geothermal anomalies and earthquakes are also discussed by using typical earthquake samples in this paper.
