摘　　要：对以地震预报为目的而开展的辽宁省盘锦、岫岩、汤池三个水氡点的长程观测资料做系统分析,总结了资料多年动态特征,并就其变化与地震活动关系进行研究;以及岫岩地震前后水氡异常变化与震源应力场关系进行了探讨。结果表明:水氡异常的幅度可能反映地震活跃期的强震活动水平;浅层地下流体观测可以反映地壳深部活动的力学过程。Based on systematically analysis to long - distance radon data of Panjin, Xiuyan and Tangchi in Liaoning province for earthquake forecast. This paper surns up dynamic characteristic on data, and research their relations to seismicity; it also discusses the relation about radon abnormity and epicenter stress field. The result indicates that radon abnormity range can reflect strong earthquake active level of earthquake active period ; shallow subsurface fluid observation can image the mechanics process of deep - crustal motion.
