摘　　要：在对沂水泉成因探讨、沂水水氡正常变化特征和主要影响因素分析的基础上 ,结合沂水水氡变化的现场分析落实和周围采样点分析结果及构造地质和流动地磁观测结果 ,对山东沂水水氡自 2 0 0 1年 3月 2 8日以来的异常变化从形成机制上进行了分析 ,认为沂水水氡的下降变化与应力活动增强。Based on the analysis of major influential factors and regular variation features of radon in Yishui Well and the discussion on the cause of formation of Yishui Spring,we have analyzed and researched the anomalous variations of water radon and its forming mechanism in Yishui Well since March 28,2001 combining with implement of the sense of radon variation and analysis results of sampling spots in and around Yishui Well as well as geological structures and mobile surveying results of geomagnetism.The results of the analysis and research indicated that the descendent variation of radon in Yishui Well are interrelated with the strengthening of stress and the intensifying of structure activity.
