摘　　要：地震前兆的干扰现象是无时不在的，各种因素的干扰是影响前兆异常定论的一个重要因素，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。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.
