摘要
多年来 ,由于人们对地热资源认识的局限性 ,只把注意力集中在地热异常区 ,即地温梯度大于 3.5℃ / 10 0m或大地热流值大于 6 2mW /m2 的地区。因此 ,地热异常区内的地热资源大部分已得到开发利用 ,而非地热异常区的地热资源远远没有得到开发利用。非地热异常区面积占平原区总面积的 80 %以上 ,所蕴藏的地热资源潜力巨大 ,如能得到开发利用 ,必将对地方经济的发展起到极大的推动作用。
For a long time past,because of the limitation of the knowledge about the geothermal resources,people only paid attention to geothermal anomalous areas,where geothermal gradients are higher than 3.5 ℃/100 m or terrestrial heat flow value are higher than 62 mW/m 2.Therefore,the geothermal resources of geothermal anomalous areas have been largly developed,while the geothermalresources of nongeothermal anomalous areas have not yet been developed.Nongeothermal anomalous areas make up over 80% of the total plain and are rich in geothermal resources.The development and utilization of the resources will surely promote the development of local economy.
