摘要:Abstract: In order to explore the transformation characteristics of the karst water system in Spring Basin with the environmental isotope tracing method which has the characteristics of fast and accurate understanding of the groundwater resources, the renewal and transformation characteristics of the karst water system in the Xin’an spring domain were studied. Taking Xin’an Spring in the domain of update transformation as example to analyze the proportion of strontium isotope and characteristics of spatial distribution in karst water, pore water and surface water in the basin, the transform relationship was explored on karst water system. By analyzing the value of tritium isotope in each discharge area of spring basin, the average age of karst groundwater was estimated and then renewability and alternation capability were analyzed. It is shown that karst water system in Xin’an Spring Basin has diversity on recharge sources, and the average age of groundwater is 107a; the renewability and alternation of the whole water resources of the spring area are frequently updating. The analysis method of environmental isotope tracing is proved to be effective in the work of exploring the water resource attributes of groundwater system.
