摘　　要：在佳木斯城区地下热水调查中,运用了水中氡活度浓度测量和土壤氡活度浓度测量综合方法,有效地克服了城市地热地质调查中的不利因素。通过对水中氡活度浓度及土壤氡活度浓度测量值的正态化变换以及原始氡活度浓度异常分析,明确了氡活度浓度异常对地下热水控制构造的指示作用。通过对氡活度浓度测量值的趋势分析,提取局部异常,综合各种异常信息,确定了城区地下热水的有利远景区。The integrated methods of radon measurements both in water and soil were used during the geothermal water survey in the region of Jiamusi city,and the disadvantageous factors were overcome effectively in the survey.By normal transformations of the radon concentrations measured in water and soil,and analyzing of original radon concentrations,the indicative function of radon concentration anomalies on the geothermal water control structures is made clear.Through trend analysis of measured radon concentration,extraction of local anomalies and integration of the different anomaly information,the prospective areas of geothermal water of Jiamusi city are determined.The result provides a basis for further detailed geological investigation of geothermal water.
