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 interference of earthquake precursors is an all-time phenomenon. The interference of various factors is an important factor that affects the conclusion of precursor anomalies. Only with the minimization of man-made disturbances, the interference of natural factors can be greatly enhanced Abnormal credibility. The fault soil gas observations developed in recent ten years are taken as the research object, and the systematic summarization is made on the observation methods of fault soil gas, interference factors and their role in the short-term earthquake prediction.
