摘要
从山东半岛所处的板块构造位置和局部的控热构造入手 ,根据地热传导的理论 ,对山东半岛温泉的地热属性进行研究分析 ,认为山东半岛温泉地热属性为濒临板缘高温地热带的板内中低温地热系统 ,它以偏高的大地热流值为地热背景 ,以局部控热构造聚敛的大地热流为热源 ,以地形高差影响和相应的水力压差作用为动力 ,入渗的大气降水吸收岩石中的热量而被加热 ,并沿断裂出露形成温泉地热水。
According to the plate tectonic location and the local heat controlling structure of Shandong peninsula as well as the theory of heat productivity of rocks, the geothermal attributes of warm springs in Shandong peninsula are discussed in this paper. It is held that these springs are of the low medium temperature geothermal system of convective type bordering on the high temperature geothermal belt at the plate edge. The local heat controlling structure turns the relatively high heat flow to its heat source. Under the influence of the topography, the meteoric water runs through faults in granite, infiltrates into rocks, circulates at depth, and continuously absorbs heat from wall rocks in the runoff process, and eventually turns into hot water. On such a hypothesis, the structural model of warm springs in Shandong peninsula has been set up.
