The study on isotopic characteristic of water in Jinxiuchuan river and its environmental significance

摘要

A environment isotope study was carried out to reveal the variation of isotope composition in Jinxiuchuan River water in Jinan. The water samples were collected during June and July for 2012 and 2013.The stable isotopes in river water have a wide range from 74.03‰ to -54.8 ‰ for SD, -10.83‰~-7.34‰ for δ~(18)O. The mean isotope values is -64.33‰ for8D, -9.01‰ for δ~(18)O. The d-excess values range from 0.3 7‰ to 16.32%o with an average value of 7.72‰. The regression slope in the regression indicates that the river water is evaporated after recharging.
