中文摘要:

      我国含水层的水文地质参数测定，主要依靠传统的抽水试验方法，然而此方法却需要花费大量的试验和钻井费用。同位素示踪方法比传统的抽水试验方法获得含水层参数的周期短、费用低，有效地提高了水文地质参数的测试精度、缩短了工期、节省了投资。为了测定柴迭木盆地西台吉乃尔盐湖地下水流速、流向、渗透系数等水文地质参数，采用单井同位素稀释法测试水文地质参数，正确确定其水文地质参数，无论对科学研究还是对生产开采，均有着重要的理论和现实意义。

英文摘要:

      Determination of hydrogeological of aquifer is mainly based on traditional pumping test in China, however, this method needs high costs for tests and well drilling. The isotope tracing method can obtain the aquifer parameters with shorter periods and lower costs compared with the traditional ways. It can efficiently improve the determination accuracy of the hydrogeological parameters, shorten the construction periods and save the investment as well. The single well isotope dilution method was applied in order to determine the hydrogeoglogical parameters of the West Taijinar Salt Lake, such as the underground brine flow rate and flow direction, permeability coefficient and so on. To determine the hydrogeoglogical parameters correctly is of great theoretical and practical significance for both scientific research and mine exploitation.
