| 摘 要： | 阐述了模拟水氡测值的影响因素，并以福州乌鸦嘴泉点为例阐述了模拟水氡异常的判识方法，为模拟水氡的异常判识提供了实例。对模拟水氡异常进行判别，充分了解水点的基本情况及所有影响因素，并了解这些影响因素对水氡的影响规律，在此基础上对干扰因素加以排除，同时用同一水点其他测项的同步变化特征来佐证该异常不是观测过程中人为及仪器因素造成的，最后进行区域背景场对比分析，再用同一区域其他水点同测项测值的同步变化情况加以佐证，以判断是否是该区域应力场所致。分析结果表明，乌鸦嘴泉出现水氡年动态畸变异常的成因在很大程度上可能是区域应力场发生变化所致。

| Abstract: | I expatiated on the influence factor of simulative water radon value.And for the spring of Crow Mouth in Fuzhou as an example,I expatiated on the judgment and identification of abnormity about simulative water radon.And I provided a factual example for abnormal judgment and identification of simulative water radon.For abnormal judgment and identification of simulative water radon,I need know fully about the basic situation and all influence factors of water observation point.And know about the influence rule of these influence factors to water radon.On basis of it,I removed these influence factors.At the same time,I made use of the synchronous change chara-cteristics of the other item in the same water observation point to prove that those abnormities aren't caused by the factitious and instrumental factors in the process of observation.At last,I contrasted and analyzed the region stress background field.I made again use of the synchronized change situation of same item value in the other water observation point of the same region to prove and judge whether they are caused by the regional stress field or not.The analysis result showed that the abnormal reason of yearly dynamic distortion of water radon appeared in the Crow Mouth spring is possibly caused by the changes of regional stress field to a great extent. |
