man">By use of the geologic remote sensing, soil radon measurement, geoelectric survey, ground temperature measurement, in combination with the related geologic information and site survey, this paper studies the mechanism of “spotted geothermal anomaly” in Longquanyi of Chengdu. All the evidences indicate that the Longquanyi fault has activities and high permeability and some fluid can rise through this fault. The main cause of the geothermal anomalies may be the earthquake “endpoint effect” of structural heat triggered by the Wenchuan earthquake.
