长期的地震预报观测研究现实表明，可靠地震短临前兆信息的探索是非常困难的，但对于实际有效的地震预报也是至关重要的．本文在分析研究震前准静大气电场异常有可能成为可靠地震短临前兆信息的基础上，利用白家疃地震台２０年连续可靠的大气电场及地震观测资料，分析总结了唐山地震后北京２００ｋｍ范围内多地震期及地震相对平静期异常与近场地震发生间的相关关系；同时，通过对近几年来预先书面上报的观测结果与该段时间内近场实际发生的地震的对比分析，结合近１０年来对近场地震书面预报意见的实效检验结果分析，论述了震前准静大气电场异常确有可能成为近场地震短临预报可靠标志的光明前景，并给出了利用震前大气电场观测资料进行地震预测的初步判定指标；最后指出，只要布有相对合理的台网（每万平方公里２～４个台）并通过进一步的探索研究，就有可能在较大地震（ＭＳ＞５）前给出近场地震三要素预测的较为可信的判定标志．
The long-term observation of earthquake prediction shows that the exploration of reliable short-term and short-term precursory information of earthquakes is very difficult, but it is also crucial for effective earthquake prediction. Based on the analysis of 20 years of continuous and reliable atmospheric electric field and seismic observation data of Baijiatuan Seismic Station, this paper analyzed and summarized the anomaly of quasi-static atmospheric electric field anomalies before the earthquake may become a reliable precursor of short-term earthquakes. In the meantime, by comparing the observed results of pre-written reporting in recent years with those actually occurring in the near-field during the period, In the recent 10 years, the paper analyzes the actual results of written predictions of near-field earthquakes and discusses the bright prospect that quasi-static atmospheric electric field anomalies before the earthquake may indeed be a reliable indicator of near-field short-term earthquake prediction. Finally, it is pointed out that as long as there is a relatively reasonable network of stations (2-4 stations per 10,000 km2) and through further exploration and research, it is possible to predict the magnitude of earthquakes in the case of large earthquakes (MS> 5 ) Gives a more credible decision flag for predicting the three elements of near-field earthquakes.
