    APPLICATION OF SHALLOW GROUND TEMPERATURE SURVEY IN GEO-THERMAL EXPLORATION: A CASE STUDY OF HOUPU AREA,XIAMEN

    • Geothermal energy is a kind of green renewable energy. How to detect geothermal anomaly area accurately and quickly has become an urgent problem. Shallow ground temperature survey can obtain ground temperature dataquickly, which can identify geothermal anomaly area. Wecarried out field experiments in the Houpu area of Xiamen by shallow ground temperature survey and obtained the temperature and in-situ thermal conductivity of 1~2 m depth. Based on the data acquired by shallow ground temperature survey, we analyzed the temperature distribution characteristics of the 2 m depth in the study area and delineated the geothermal anomaly area. We established aprediction model of ground temperature based on one-dimensional steady-state heat conduction theory. According to the field experiment data of shallow ground temperature survey, we predicted the temperature distribution of the constant temperature layer in the study area and compared it with the measured temperature. The results show that the prediction model of ground temperature is accurate and the temperature contour map of constant temperature layer can more accurately reflect the actual situation of geothermal anomaly. Shallow ground temperature survey and it's data analysis method can be used as an effective means in the early stage of geothermal exploration.
