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 p H was 5.4,varied from 4.6 to 6.9.Ca;and NH;were the major cations,and SO;was the dominant anion.Neutralization factors show that the acid was mainly neutralized by Ca;,NH;and Mg;.Investigations of correlation coefficients and enrichment factors revealed that Ca;and Mg;were mainly crust origins,and NH;was from agriculture and livestock manure.SO;and NO;were mainly from anthropogenic sources.
