摘　　要：三水转化是现代水文学中研究的热点,传统的研究方法多集中在介质场、水动力场和水化学场等方面。环境同位素技术作为一种新兴技术已经在水文地质领域逐渐被广泛应用。本文根据环境同位素的基本理论,运用D1、8O、T同位素研究了新疆玛纳斯河流域三水的相互转化关系、转化比例等方面,得出从山区到沙漠区共经历了4次转化,不同地段的转化方式和转化量不尽相同,进一步阐述了水文地质条件,为该地区的水资源评价奠定了基础。The study on the transformation among precipitation-surface water-groundwater is a hot hydrographs, and the previous study mostly focus on the aspects of dielectric filed, hy point in c field, hydrochemistry and so on. The environmental isotopes are wildly applied in the hydrogeology field as a new technology. According to the basic theory of environmental isotopes, the transforming relationship and proportion of the precipitation-surface water-groundwater in the valley of Manas River are studied by using the isotopes D, ~a0 and T. It is found that the precipitation-surface water-groundwater transforms for four times from the mountain area to the desert area and the transforming forms and quantity are different in different sectors. conditions are further expounded, which supplies a definite base for the evaluation of water resources in the area.
