摘要
通过对洱源盆地内温泉点进行实地调查,确定其分布情况,并用FD—105水氡仪对水氡背景值进行观测研究。调查分析结果显示,洱源盆地内温泉点自北向南呈散点分布,一直延续到右所盆地西侧,主要分为牛街—三营、洱源县城和下山口—右所3个片区,温泉水氡值自北向南逐渐递减,测值在3.9~130.3Bq/L,且牛街—三营片区的水氡值较另外2个片区高。综合以上结果,本次研究提供了洱源盆地温泉水氡背景值分布特征,为该区域内未来寻找新的测点或备用测点提供参考。
The distribution of hot springs in Eryuan basin was determined by field investigation,and the background value of water radon was observed by FD-105 water radon meter. The survey and analysis results show that the hot springs in Eryuan basin are scattered from north to south and extend to the west of Yousuo basin. They are mainly divided into Niujie-Sanying,Eryuan County and Xiashankou-Yousuo. The water radon value of hot spring water decreases gradually from north to south,the measured value ranges from 3.9 to 103.3 Bq/L,and the water radon value in Niujie-Sanying area is higher than that of the other two areas. Based on the above results,this study provides the distribution characteristics of radon background value of hot spring water in Eryuan basin,and introduces a reference for finding new or alternative measuring points or preliminary measuring points in this region in the future.
