摘要

分析了１９９９年长乐筹东土壤氡气（土氡）变化特征，认为４～６月该测点土氡异常特征与９月２１日的台湾南投Ｍs７．６级地震有关，７～９月的测值变化是由于降雨过多引起的，并介绍了９月下旬后该测点的土氡变化特征。
In this paper, the characteristic of the change of soil - gas radon in Choudong, Changle city in 1999 was analyzed. The anomalous characteristic of soil - gas radon from April to June of 1999 was related with the Nantou earthquake Ms7.6 on September 21, 1999 of Taiwan Province. But the chang of soil ?gas radon from July to September of 1999 is the result of excessive rainfall during this period. The change characteristic of soil - gas radon after the last third part of September was introduced
