The evaluation of shallow geothermal energy resources in Chongqing

Abstract：Based on investigation and study of the shallow geothermal energy adaptive partition in the main urban area of Chongqing, combined with the corrected rock and soil thermal physical property numerals, the authors conducted the shallow geothermal energy resource evaluation in the main urban area of Chongqing. The evaluation included the shallow geothermal energy heat capacity and statistics of available resources in appropriate areas. In this way the distribution of shallow geothermal energy resources in nine districts of Chongqing was detected so as to effectively evaluate heat storage capacity of underground shallow space in the main urban area of Chongqing. The results obtained provide a reliable basis for the development and protection of the shallow geothermal energy resources.
