摘　　要：通过对甘肃省各种前兆资料的分析,发现玉门5.9级地震前地电、地磁、应力和应变、地下流体及水氡和气氡等多种测项都有异常显示。研究各个测项的异常时间、幅度和异常台项的分布后,得到此次地震的中期和短期异常特征,对中强震的短期预报有一定参考意义。Analyzing various precursor data in Gansu province area, we found that there are anomalies appearing in geoelectricity, geomagnetism, stress and strain, underground flow, water-radon and escaping-radon, etc. before Yumen MS5.9 earthquake. After researching anomalous appearing date, range and distribution of every item, the moderate-term and short-term anomaly feature are obtained on this earthquake, and the result is helpful to short-term prediction of moderate strong earthquake.
