摘　　要：本文研究了澜沧-耿马7.6级地震震中周围700公里范围以内,地电阻率异常现象。由于受该区的地质构造及物性条件控制,震前只在某些地电台上记录到了较明显的地电阻率趋势下降异常,再次证明地电阻率法作为地震预报前兆方法存在的重要意义。The Abnormal phenomena of earth resistivity observed within the range of 200-700 km around the epicenter before the Lancang-gengma M 7.6 earthquake have been studied in this paper, Because of the tectonic setting and material property conditions governing the appearance of such phenomena, only some of the geoelectric stations in this region have recorded relatively clear anomalies showing a drop tendency of earth resistivity before the earthquake. This, again, demonstrates the significance of the earth resistivity observation as an existing method for monitoring earthquake precursors.
