【摘要】 自然界的各种水体(降水、地表水、地下水、土壤水)中都广泛存在着环境同位素,同位素技术在地下水中的应用趋于成熟,但在地表水中的应用不是十分广泛。从基流分割、径流平均传播时间、水环境三个方面重点论述环境同位素在地表水应用,并结合研究现状分析存在的问题和探讨应用前景。更多还原

【Abstract】 Environmental isotope exists extensively in various kinds of water,such as precipitation,surface water,groundwater,soil moisture and plant water.Isotope technology application in groundwater water becomes more and more mature,but is not widely used in surface water.The study aimed to discuss the recent advancements of isotope application in surface water through base flow separation,average transmit time of runoff and water environment these three aspects.It also pointed out the existing problems and research prospects about the isotope application in surface water.更多还原
