達(dá)里諾爾湖氫氧同位素與水質(zhì)水量關(guān)系研究
[Abstract]:In this paper, the characteristics of water quality index and stable isotope distribution in the ice sheet and water body of the lake during the glacial period were studied by taking Darinole Lake, Inner Mongolia, as the research object. The relationship between water quality index concentration and isotopic content in the ice period is analyzed. The distribution characteristics of water quality indexes in lake water and ice body are indicated by the distribution characteristics of isotopes in lake ice period for the first time. The isotope tracer can be used as an evaluation method to prove and predict the water quality index. Further using isotope tracer water cycle, by analyzing the isotopic linear relationship in the Dali Lake area, and combining with the total dissolved solids to explore the supply relationship of Dali Lake, and using the stable isotopic material balance model to estimate the evaporation of Dali Lake, Indirectly indicates the problems in the process of water circulation. The main conclusions are as follows: during the period of ice closure, the average concentration of nutrients in the water of Lake Daly is relatively high, which has far exceeded the five water standards of the national standard. Due to the obvious thermodynamic fractionation effect of isotopes during ice formation and the recharge of Gongge River, the contents of hydrogen and oxygen isotopes in the ice body of Lake Daly are much higher than those in the water body. It is the first time that isotopes have a significant negative correlation with nutrients in ice-water and ice bodies. The quantitative equations are: TN=-0.2825 D-6.0083 and TP=-0.0805D-1.2395,. The indicator of water quality by hydrogen and oxygen isotopes during ice closure is realized. The stable isotopic contents of different water bodies during the water cycle of Lake Dali are analyzed by regression analysis, and the atmospheric precipitation line 未 D ~ (6) C ~ (6) 6866 未 18O-8.3124 (R _ (2) O _ (0.7908) and the evaporation trend line 未 D ~ (4) 4.5349 未 180-27.054 (R _ (22) 0.9009) in the Dali Lake region are derived. By analyzing the linear relationship and the hydrogeological conditions of total dissolved solids and regions, it is concluded that groundwater is the main recharge source of Dali Lake. Based on the stable isotope method of water body, the stable isotope mass balance model is used to estimate the evaporation of Dali Lake. This method provides a new method for the study of water circulation in Inner Mongolia.
