摘　　要：地热异常区的探测对于地热能开发利用至关重要。利用2 m测温法和相关仪器对厦门东山某热泉地区进行实地探测,获取1~2m深度地层温度和导热系数数据,绘制研究区2m深度温度等值线图和浅层热流密度分布云图,圈定地热异常区。运用一维稳态热传导模型对研究区20 m深度地温进行反演,并与研究区20m深度实测温度进行对比分析。结果表明,2m测温法对地热异常区探测效果明显,一维稳态热传导模型对于20m深度地温的预测结果与实测结果较为一致。该方法可以作为地热探测初期的有效手段。Geothermal anomaly areas exploration is essential for the development and utilization of geothermal energy.2-meter temperature survey and associated apparatus are used to get temperature and thermal conductivity data of 1-2mdepth in a hot springs area of Dongshan,Xiamen.Then temperature contour map of 2mdepth and heat flow density distribution map of shallow layer are drawn,geothermalanomaly areas of research area are delineated.The one-dimensional steady-state heat conduction model is used for ground temperature inversion of 20 m depth.Then inversion results are compared with measured temperature of 20 mdepth.The results show that the effect of 2 meters temperature survey for geothermal anomaly areas is obvious and prediction result of one-dimensional steady-state heat conduction model is consistent with measured results.This method can be used as an effective mean for early stage geothermal exploration.
