摘　　要：通过对车村—鲁山大断裂与河南鲁山五大温泉关系的探讨,并应用激电测深法勘探、RGIS软件反演解释技术,查明下汤温泉东西两侧1 500 m范围内水文地质条件,认为下汤温泉即受控于近东西向车村—鲁山断裂(F1),也受控于北东向F4断裂。前者为一级控热导热构造,是深部热源向上对流的主要通道;后者为二级控热导热构造。在地形和水头压差的驱动下,地下水沿着断裂带自西向东缓慢的运移,期间受地壳内部热源传导,在排泄区受到北东向F4断裂的控制,向地表运移,出露成泉。By means of electrical sounding and inversion interpretation with RGIS, the authors investigated the relationship between Xi-atang warm spring and Checun-Lushan fault and found out the hydrogeological conditions within 1 500 m on both east and west sides of Xiatang warm spring. The results reveal that Xiatang warm spring is controlled by the EW-trending Checun-Lushan fault （ F1） , and al-so affected by the NE-trending F4 fault.. The former fault is the heat-conducting structure of level 1, and is also the major passage for upward convection of the deep heat source;the latter fault is the heat-conducting structure of level 2. Driven by the topography and the difference of hydraulic head pressure, the underground water migrates slowly along the fault zone from the west to the east. During the movement, the underground water is affected by the earth＇s internal heat-conduction and the NE-trending F4 fault and flows to the sur-face and is exposed as springs in the discharge area.
