摘要
为了探讨银川市浅层地温场分布特征及影响浅层地温场的控制因素,采用自动和人工相结合的方法对银川市90~200 m地温监测孔进行监测.数据显示,200 m以内浅层平均地温梯度一般为1.5~4℃/100 m,高地温带呈NNE向展布于银川市区中部,形态分布与该区重要隐伏活动断裂走向基本一致.研究表明,银川张性断裂是银川市浅层地温场分布的控制因素,是造成浅层地温异常的主要因素.
In order to investigate the distribution characteristics of the shallow geothermal field and control factors in Yinchuan city,the combination method of automatic and artificial is used to monitor the hole temperature of 90~200 m underground in Yinchuan.Data show that the area average geothermal gradient is 1.5~4 ℃/100 m within 200 m,higher geothermal gradient value is located in middle part of plain from north to south,it’s distribution characteristic is basically consistent with major concealed activity fault.Research show that Yinchuan fault is control factor for the distribution of the shallow geothermal field,is the main factor for the unusual of the shallow geothermal.
