Study on sources of chemical elements and geochemical susceptibility of a typical karst spring
摘要
Abstract
To quantitatively study the prominent geochemical susceptivity and vulnerability of a karst spring in typical karst areas, the geochemical susceptibility and sources of chemical elements in Shuifang Spring, Jinfo Mountain in Chongqing was analyzed by using hydrochemical data from January 2016 to December 2016. The results show that chemical types of Shuifang Spring were Ca-HCO3 and Ca-HCO3·Cl. Under the combined influence of karst processes and human activities, the major anions and cation were HCO3-, Cl-and Ca2+. Cl- mainly come from human pollutants caused by tourism activity, and SO42- mainly comes from the effects of sulfuric acid rain. Due to seasonal change of karst processes, HCO3- and Ca2+ became the most sensitive ions. Under the influence of tourism activities, the geochemical susceptivity for major elements except for NO3- in Shuifang Spring has increased in the order of HCO3->Ca2+>Na+>SO42->Cl->NO3- = K+>Mg2+.The chemical features of karst spring are more sensitive because of human activities.Measures such as reducing and purifying the pollutants of human activities, improving the awareness of environmental protection of tourists and other related measures are strongly suggested for the protection of karst spring.关键词
