Based on analysis of geologic foundation record about pingzhuang basin, a lot of sino - foreign geothermal geology record and investigation of field geology, measuring of ground temperature in person and geo - chemical analysis of ascension spring, gushing water of fault, the fact that the anomaly of geothermal gradient of pingzhuang basin, which is in region of low geothermal gradient, is caused by redistribution of conduction - oriented geothermal heat flow which is result from upheaval and depression of basin foundation bed is pointed out. after the field of ground temperature is simulated under the background of conduction - oriented geothermal heat flow by means of ansys, the characteristic of ground temperature distribution of top surface of basin foundation bed ( yixian team ) is revealed. the sound condition of transmissibility fault and feeding water source, which are imperative in formation of the low - medium temperature geothermal system of convective type, is possessed in pingzhuang basin
通過對平莊盆地基礎地質資料、國內外大量地熱地質資料的分析和野外地質調查、礦井實測地溫以及上升泉、斷層涌水的地球化學分析等工作基礎上，指出地處低地溫梯度背景區的平莊盆地地溫梯度異常是由於盆地基底隆起和坳陷引起傳導型大地熱流再分配所致；運用州sys數值模擬了大地熱流向地表傳導背景下的盆地地溫場，從而揭示了盆地基底（義縣組）頂界面地溫分佈特徵；闡明了盆地具有形成中低溫對流型地熱系統所必需的導水斷裂、補給水源等的良好條件，中低溫對流型地熱系統是地熱勘查的主要對象；圈定了平莊盆地北部朝陽溝?駱駝營子地熱勘查遠景區。 -
