摘要
应用环境同位素方法计算了山西省东南部辛安村泉域中奥陶统、奥陶－寒武系岩溶地下水年龄各为８０ａ和８４ａ，储量各为２．５７×１０￣（１０）ｍ￣３和３．１５×１０￣（１０）ｍ￣３；计算了泉域碳酸盐岩补给区降水入渗系数α＝０．２１；河流渗漏量为２．０５ｍ￣３／ｓ；泉域石膏剥蚀速率Ｍ＝２．２１ｍｍ／ｋａ。
It is estimated for Xinancun spring basin of the southeast of·Shanxi Province by environ-mental isotopic method that the ages of karst ground water from Middle Ordovician andCambrian-Ordovician aquifers are 80 and 84 years,their reserves 2.57×10￣(10)and 3.15×10￣(10)m￣3,respectively,The coefficient of infiltration is 0.21 in the recharge areas of carbonaterock regions.The river seepage is 2.05m￣3/s.The denudation rate of gypsum represents 2.21mm/ka.
