摘要
洛阳盆地是一个较大型断陷盆地,是一个完整的水文地质单元,地下水资源丰富,是当地主要的供水水源,地下水类型主要有松散岩类孔隙水、碎屑岩类孔隙裂隙水、岩溶裂隙水,盆地区地热水资源比较丰富。根据洛阳盆地内稳定同位素和放射性同位素的测试结果,对盆地内地下水的补给来源和形成年龄进行了分析,结果表明:洛阳盆地岩溶地下水主要接受周边山地区基岩山区大气降水的入渗补给,其地下水形成年龄在几万年以内;盆地内松散岩类浅层孔隙地下水主要接受大气降水和地表水的补给,其形成年龄为几十年;盆地区地热水主要接受周边基岩山区地下水的径流补给,其形成年龄为几千年到几万年。
Luoyang basin with complete hydrogeological unit is a relatively large rift basin,which is rich in groundwater resources that provides local major water supply. The types of groundwater are mainly distributed with loose rock pore water,clastic rock pore fissure water and karst fissure water. Simultaneously geothermal water resources are relatively rich in the basin area. According to the results of stable isotope and radioisotope in the basin,the recharge and formation age of groundwater in the basin had been analyzed. The results show several conclusions: the karst fissure water mainly is recharged by the precipitation infiltration from the bedrock mountainous area which formation age is within tens of thousands of years; the loose rock pore water is mainly composed of precipitation and surface water which formation age is several decades; the geothermal water is mainly recharged by the underground runoff from the surrounding bed rock which formation age is from thousands of years to tens of thousands of years.
