Based on the basic geology, hydrogeology, engineering geology, geothermal geology and ground source heat pump(GSHP) engineering of the work space, the thesis studies the local shallow geothermal energy. Three conditions of the attribute index for the suitability zoning of the northwest of Shandong are determined, namely, hydrodynamic condition, geological and hydrogeological condition and geological environment condition. The assessment result is that the total area of the suitable zone is 205.88 km^2, that of relative suitable zone, 1 407.76 km^2, and that of unsuitable zone, 286.8 km^2. The result conforms to the real development situation and provides experience for similar regions needed for selecting and assigning a value to suitability zoning of GSHP. 展开更多
