英文摘要: Abstract(#br)Acid deposition and algae blooms have resulted in great changes in the water chemistry of Taihu Lake; however, there have been few calculated results to describe these processes. Here we used a mass balance model to estimate base cation losses and evaluate the model applicability in this intensively human-impacted watershed based on a long-term database (1985–2015). The results showed that carbonate weathering induced Ca 2+ and Mg 2+ losses in the watershed were responsible for the increased ion net reaction (INR) of Ca 2+ and Mg 2+ in the lake. While the increase of K + and Na + were not appropriate to provide independents check on the mass balance model because they generally entered the lake as human discharges, not reflecting change of the geochemical process in the...
