Study on the Distribution Characteristics of Geothermal Gradient in Shandong Province

摘要:

在充分搜集山东省区域地质、构造地质、地热地质及地热遥感解译资料等基础上，开展了山东省地温场现状调查、1∶50万地热遥感解译和测温工作，根据收集资料程度，提出计算地温梯度的方法，计算了整个研究区地温梯度；评价了各个地热区地温梯度的分布规律，并从大地构造、基岩起伏、岩浆活动、地层岩性、断裂构造、地下水活动等方面分析了影响地温场分布的因素，讨论了浅部地温场与深部构造的关系，总结了研究区各区地温梯度的分布特征。

Abstract:

On the basis of fully collecting regional geology, geothermal geology, structural geology, geothermal well completion report and geothermal remote sensing interpretation data in Shandong province, survey on present condition of geothermal field in Shandong province,and geothermal remote sensing interpretation with the scale of 1∶500000 have been carried out. According to the degree of data collection, a method for calculating the geothermal gradient has been put forward, and geothermal gradient of the whole study area has been calculated. The distribution rules of geothermal gradients in various geothermal areas have been evaluated, and the factors affecting the distribution of geothermal fields have been analyzed from the following aspects, such as geotectonics, bedrock fluctuations, magmatic activity, stratigraphic lithology, fault structures, and groundwater activity. The relationship between shallow geothermal fields and deep structures has been discussed, and the distribution characteristics of geothermal gradients in various regions of the study area have been summarized.
