Based on the geochemistry and geophysical detecting data of the main control structure (namely, the August First Reservoir to Shanggan Fault), shallow geotemperature surveying results and the geophysical exploration data of the Zhongfang-Hongtang-Wulongjiang geothermally-disturbed zone in Fuzhou geothermal field, it is considered that the underground heat in the Yixu and Luozhou area of south Fuzhou is still controlled by the August First Reservoir to Shanggan buried fault. The geothermic anomaly is obvious in the Yixu, Lüxia, Luozhou and Huaian areas of
