| 摘 要： | 江苏地温分布的一般规律是：坳陷区地温高于隆起区，坳陷区中次级正向构造高于负向构造，隆起区中则相反，此外，地温随深度加大而增高，全省的第Ⅱ、Ⅲ、Ⅳ含水层中，共划盼出热水异常３５个，按平面分布的重叠性归并为２１个地热异常，其中大部分可归纳为个异常带，扬子准地台区是本省地热异常的主要分布区。

| Abstract: | The general distribution law of geotemperature is that the geothermal gradient of down-warping area is higher than that of upwelling area and the geothermal gradient of medium or secondary grade positive strutures in down-warping area is higher than that of negative structures.The gradient distribution in upwelling area is opposite from the down-warping area.The deeper the depth,the higher the geothermal gradient.There have been divided into 35 thermal water anomalies in No.II,No.III and No.IV aquifers and 21 anomalies were merged based on the superimposed plane distribution in which most of anomalies fallen into 5 anomaly zones in Jiangsu.Yangtze paraplatform is a major distribution region for geothermal anomaly. The important and control factors on geothermal distribution are regional tectonics,deep crust sturctures,thermal physical properties,magma and underground water activity.The thermal distribution in Jiangsu are controlled largely by tectonic systems since Yanshanian movement,especially Neocathaysian and Cathaysian structural systems.Located in second mole track of Neocathaysian system,the enclosed conditions of geotemperature in Jiangsu are imperfect.The heat sources of geotemperature anomaly and geothermal fields originate from quantity of heat which is formed by natural temperature increment in depth.The active faults constitute pathway for geothermal water mainly then, the geothermal anomaly is closely related to seismic activity. |
