摘　　要：曲阜市近山前地区基底地层是理想的热介质,区域主控断裂对地温场起明显控制作用,含水岩组和地下水运动为地热提供了理想载体。以岩石导热特征,可将曲阜地区地层分为2 大类:即热基底地层和热盖层地层。前者热导率为25.41×10-3~36.30×10-3T/cm·s·℃;后者为18.92×10-3~23.99×10-3 T/cm·s·℃。地热资源赋存于受断裂构造控制的槽形地带内,属典型的构造—盆地增温型。Basement strata in subpiedmont area of Qufu city is good thermo-medium, major regional controlling fault controlled geo-temperature field evidently, water-bearing formation and underground water movement provide ideal mounting for geotherm. According to thermal-conductivity characteristics, strata in Qufu area can be divided into 2 types: that is geothermal basement and geothermal covering. Heat conductivity of the former is 25.41×10^(-3)~36.30×10^(-3)T/cm·s·℃, while the later is 18.92×10^(-3)~23.99×10^(-3)T/cm·s·℃. Geothermal resource occurs in trough belt controlled by fault structure, which belongs to typical structure-basin temperature-increasing type.
