摘　　要：记录和描述了近35年来河南林州地区的地光异常现象,发现林州地光异常的出现与林州及其邻近地区中小地震的发生存在一定的对应关系。结合林州地区的地质构造特征和岩性(石英岩)分布特征对地光出现的机理进行了讨论。探讨了地光异常的观测和利用其进行地震预报的尝试。The phenomena of earthquake light in nearly 35 years in Linzhou city of Henan province are summarized and described in this paper.It is found that there is a corresponding relationship between the earthquake light anomaly appearances and occurrence of moderate-small earthquakes in Linzhou area or its adjacent area.The forming mechanism of the ligh is analyzed with the geological structure and the distribution of lithology（quartzite） in Linzhou area.The observation of the ligh and how to use it in earthquake prediction are discussed at last.
