摘要： 地震前兆的干扰现象是元时不在的,各种因素的干扰是影响前兆异常定论的 个重要因素,只有在最大限度地降低人为干扰的基础上,进行自然因素的干扰排除,才有可能大大提高异常的可信度。以近十年发展起来的断层土壤气观测为研究对象,对断层土壤气的观测方法、干扰因素以及在地震短临预报中的作用等方面进行系统总结。

Abstract: The disturbance phenomenon of earthquake precursors universally occurs at any time, and the disturbance of different elements is a vital factor affecting the identification of pre­cursory anomalies. Therefore, only eliminating the disturbance of natural factors, based on reducing artificial disturbance as largely as possible, can we greatly increase the credi­bility of earthquake. anomalies. Mainly aimed at soil gas in fault zones, the observational technique has been developed in recent years. The disturbance factors of fault soil-gas measurement as well as the role of fault soil-gas in impending earthquake prediction are systematically summarized in this paper.

Key words: Fault gas, Precursor information, Disturbance factor, Impending prediction
