摘要
分析了昌黎井2004年洗井前后水位、水氡的趋势动态特征,认为洗井是造成水位和水氡两者趋势变化不同步的主要原因之一。经过观测环境调查,判定2009年以来水位趋势下降并打破年变规律与附近温泉井抽水有关。
This paper analyzes the long-trend variations of water level and water radon in Changli well.The results indicate that the asynchrony between the long-trend variations of water level and the long-trend variations of water radon is caused by well washing.According to our survey on observation environment of the well,the long-trend decreasing variation of water level since 2009 is concerned with water dumping in a hot spring well.
