摘要

在龙门山断裂带中段的北川地区进行了土壤氡浓度随时间的动态变化定点观测。初步研究资料表明：土壤氡浓度变化与气象因素有密切的相关性；场地环境对氡浓度有一定的影响；探片照射方式不影响探测结果；土壤氡浓度变化能较好地反映北川及邻近地区地震活动信息。
The dynamic variation of the Radon-density in soil with the lapse of time has been obtained from surveying at fixed position in Beichuan area along the middle part of the Longmenshan fault zone.The results of tentative research make know:The Radon-density varation is closely related to the weather factors. the environment of the place influences on the Radon-density,The irradi-ating way of sounding picture does not influence on the sounding results. The Radon-density vari-ation fairly reflects the earthquake activity in Beichuan and neighbouring area.
