摘要
在分析郑州市超深层地下水的地质、水文地质条件的基础上,通过测定其同位素的含量,得知该地下水主要来源于郑州市西南低山丘陵区的降水补给,其平均年龄为43.2a.二维地下水运移模型的模拟结果表明,郑州市可开采地下热水资源为136.89×104m3/a,城区已超采,城郊则有一定潜力.图4,表1,参10.
Based on the analysis of geological and hydrogenological condition of the super-deep geothermal waters in Zhengzhou city,it is proved by the concentration of oxygen and hydrogen isotopes that the super-deep geothermal water derived from the precipitation near the hill region in the southwest of Zhengzhou city and it is at the age of 43.2 a.The results of 2D numerical modeling of groundwater flow field shows that there are groundwater resources of 136.89×10~4m^3/a,but over-exploitation has occurred in the city area and there are some potential to exploitation in the suburb area of Zhengzhou city.4figs.,1tab.,10refs.
