摘要：

The chemical composition of rainwater has been studied in a karst rural area from September 2012 to August 2013 in Guizhou Province, Southwest China. The results indicated that the VWM value of pH was 5.4, varied from 4.6 to 6.9. Ca2+ and NH4 + were the major cations, and SO4 2− was the dominant anion. Neutralization factors show that the acid was mainly neutralized by Ca2+, NH4 + and Mg2+. Investigations of correlation coefficients and enrichment factors revealed that Ca2+ and Mg2+ were mainly crust origins, and NH4 + was from agriculture and livestock manure. SO4 2− and NO3 − were mainly from anthropogenic sources. © 2017, Science Press, Institute of Geochemistry, CAS and Springer-Verlag GmbH Germany.
