本文阐述了模式识别方法的原理及其在综合地震预测中的实用性与可行性。文中以华北和西北地区为例,提取了中强地震前的前兆与地震活动异常特征,根据计算结果估计,未来两年内在西北甘青交界武威—西宁以西(37°—38°N,101°—102°E)范围内可能发生6级地震的预测意见。 This paper describes the principle of pattern recognition and its practicability and feasibility in synthetic earthquake prediction. Taking North China and Northwest China for example, the anomalous features of precursory and anomalous seismic activity before the strong earthquakes are extracted. Based on the calculation results, it is estimated that in the next two years, at the west of Wuwei-Xining in the northwestern part of the Qinghai-Xizang (37 ° -38 ° N, 101 ° -102 ° E) range of possible magnitude 6 earthquake prediction.
