Abstract：Taking theChenxikou geothermal fieldinDongpingtown，AnhuacountyHunanprovinceas theresearcharea， aregression model was constructed toquantifythe corelation between tectonic fracture parameters and underground hot waterresource characteristics bycomprehensively using multi-source data such as geological survey，geophysical exploration，reholemeasurement，logingnalysis，drologicalexperiments，ndsotopetesting.Thesultsidcateat the tectonic fracturesystemplaysadominantrole intheformationofundergroundhotwater，depfaultsprovidechannels forthermalenergyanddeephydraulicpower，whileshallowfaultsundertakethefunctionofsupplyingandguiding water，the intersectionareaof thethreecontrolstheenrichmentofhotwater;thefracturedensityissignificantlypositivelycoelated withthethicknessofthethermalreservoir，ndthegeothermaleatingateinthestructuralintersectionzoneismuchigher than that in a single fault section.
