摘    要:利用长白山玄武岩区Landsat TM5遥感影像数据,对研究区地表温度场进行了解译。综合分析研究区地表温度场、温泉和地热井分布特征、布格重力场和磁场四个因子,采用判别分析方法建立并验证了判别函数,对研究区地热水异常分布进行了识别。采用分段均值法研究了区内7条主要断裂与地热水异常的关系。研究表明,研究区地热水异常主要分布在环长白山天池火山口区域,松江河—抚松县以及二道白河—松江镇一带的抚松盆地和松江盆区,仙人桥地区和长白县—十四道沟一带的长白盆地区;断裂带和地热水异常区的分布有较好的相关关系。北西向的断裂带对地热水异常区分布的影响程度均是南西侧高于北东侧,且在断裂带处存在地热水异常区域;北西西向的断裂带对北东侧地热水异常区分布的影响程度高于南西侧;北东向和近东西向的断裂带受长白山天池火山的影响,在近天池火山口的区域,均存在地热水异常区域。

关 键 词:断裂    地热水异常    分段均值法    Landsat  TM5遥感影像    长白山玄武岩区    地表温度场    布格重力场    磁场

Abstract:The surface temperature field of the Changbai Mountain basalt area was interpreted using the Landsat TM5 data. The geothermal anomaly areas were identified by the discrimination analysis, in which the comprehensive analysis of the surface temperature field, hot springs and geothermal well distribution characteristics and gravity field and magnetic field were carried out. The relationship between 7 main faults and the geothermal water anomaly was evaluated with the subsection mean method. The results show that the geothermal water anomaly areas can be divided into four regions, including around the Changbai Moutain Tianchi volcano region, the Songjianghe country-Fusong county-Erdaobaihe country-Songjiang country regions (the Fusong basin and Songjiang basin), the Xianrenqiao region, and the Changbai county-Shilidaogou country region (the Changbai basin). The spatial distribution of geothermal water is in good correlation with the faults. The influence degree on geothermal water of the SW-trending faults is higher in the SW sides than in the NE sides of the faults, and the geothermal water anomaly is found in the fault zones. The influence degree on geothermal water of SW-trending faults is higher in the NE sides than in the SW sides of the faults. There is geothermal water anomaly near the NE-trending and EW-trending faults, which were influenced by the Changbai Mountain Tianchi volcano.
