摘要： 根据地表水体样品、地下水样品的同位素测试结果,绘制δD δ18O关系图、δ18O H关系图,从而对东北平原西部山前台地区的地下水补迳排关系进行分析·获得该地区雨水线方程δD=7 1781δ18O-8 1151;高程效应关系式δ18O=-0 0049H-8 209;同时认为大兴安岭山区是该区地下水的补给区,补给源是大气降水,区内地下水循环迟缓,主要为1991年以来大气降水补给;地下水形成年龄在3 26～10 6年之间;地下水形成时年平均气温略低于现代年平均气温·

Abstract: Based on the testing results of isotopes for collected samples of surface water and groundwater, the relationships of δD to δ18O and δ18O to H were plotted so as to analyze the relations among the recharge, runoff and discharge of groundwater in the pediment tableland region. The following equations were thus given, i.e., for the regional rainwater relation line δD=7.1781δ18O-8.1151 and for the elevation effect relation line δ18O-0.0049H-8.209. Meanwhile, the Greater Xing'an Mountains are reckoned the recharging areas of groundwater sourcing from meteoric water. Inside the areas the circulation of groundwater is rather slow and the recharging source is mainly the meteoric water accumulated since 1999 and formed within 3.26-10.6 years. The annual average temperature during the formation of groundwater is a little bit lower than that at present.
