摘要
通过对海口水化台 ＺＫ ２６井不同层位水温数字化观测资料的分析，发现水温随深度的增加呈线性上升趋势，在第二含水层的 １２０－ １５０ ｍ段可能有一热水活动带，而 １５０ ｍ向下至 １５８ｍ段水温快速下降，并在该段观测到大致与水位反向的水温日变形态。此外，该并不同层位的水温还显示出不同的长期变化特征，并在 １５３ ｍ含水层和 ３３６ ｍ非含水层内皆不同程度地观测到井区３００ ｋｍ内 ＭＬ≥４．０级地震的可能前兆异常。
Based on the analysis of digitized observation of the water temperature various beds at ZK 26 well in Haikou, the relationship between the water temperature and the depth of well is discussed, and the dynamic performance of well temperature in different depths is analyzed. According to these, an anomalous hot aquifer bed is found, and some water temperature anomalies as earthquake precursor are also summarized and collected.
