在分析研究区水文地质条件基础上,根据同位素测试结果,重点分析了地下水、泉水及地表水氢氧稳定同位素和氚同位素的分布特征。潜水δD变化范围为-87.71~-75.40‰,δ18O为-12.80~-10.91‰。承压水δD为-90.44~-65.57‰,δ18O为-13.08~-8.17‰。地下水氚浓度主要集中在15~30TU范围内,绝大部分地下水为1953年以前所补给。地下水与地表水均起源于当地大气降水。潜水与承压水水力联系较强,潜水与承压水属于同一含水系统,在开发过程中要十分注重保护这一含水系统,防止过度开发导致含水系统遭到破坏。
Based on the analysis of hydrogeological conditions in the study area, the distribution characteristics of hydrogen and oxygen stable isotopes and tritium isotopes of groundwater, spring water and surface water are analyzed emphatically based on the isotope test results. Diving δD range of -87.71 ~ -75.40 ‰, δ18O -12.80 ~ -10.91 ‰. The pressure water δD is -90.44 ~ -65.57 ‰, and δ18O is -13.08 ~ -8.17 ‰. Groundwater tritium concentration is mainly concentrated in the range of 15 ~ 30TU, the vast majority of groundwater supply before 1953. Both groundwater and surface water originate from local precipitation. Diving and confined water have strong water-hydraulic connection. Both submersible and confined water belong to the same water-bearing system. During the development, great attention should be paid to protecting this water-bearing system and preventing over-exploitation resulting in the destruction of the water-bearing system.
