摘要: 水化学分析结果表明,鞍山市倪家台地下热水属于HCO3·SO4-Na和SO4·HCO3-Na型水,且含有氟、锶和二氧化硅等多种矿物成分.由构建的硅-焓混合模型得出倪家台地区地下热水已有大量冷水混入,且混入比例介于67%—83%之间,水温下降的诱因是该区域过量开采地热水,在这种人为的长期干扰作用下,增大了上部含水层冷水对下部地热水的补给量,对今后可持续利用该区域地热资源构成了严重的威胁.

Abstract: Hydrochemistry analysis results has indicated that the geothermal water in Nijia-Tai belongs to the types of HCO3·SO4-Na and SO4·HCO3-Na.It also contains a great deal of minerals such as fluoride,strontium and silicon dioxide.By the silicon-enthalpy mixing model,it was deduced that the geothermal water in Nijia-Tai has been mixed with the upper cold groundwater and the mix proportion is between67% and 83%.The over-exploitation to the geothermal water results in its temperature drop.With the long-term disraption by human-beings,the recharging amount of upper cold aquifer to the lower geothermal water is increasing,which,if not changed,would seriously threat the sustainable utilization of geothermal resources in this area.
