摘要
利用南昌农田保护区2005～2006年土壤要素、酸雨pH值及空气SO2浓度的监测资料，进行了土壤酸性、酸雨pH值、空气SO2三者间的相关分析，结果表明：空气SO2浓度与酸雨酸性强度有极显著的负向关系；农田土壤pH值与同期的空气SO2、酸雨pH值具有一定的相关性。研究认为，空气中SO2排放、酸雨是南昌农田土壤酸化的主要原因。
The monitoring data of soil acidity, pH -value of acid rain, and atmospheric sulfur dioxide （SO2 ） concentration were used and their correlations were studied based on measurement of soil properties and acid rain continuously conducted in the protected croplands in Nanchang, Jiangxi province and atmospheric SO2 concentration observation made by Nanchang Environmental Monitoring Station during years 2005 and 2006, The result showed that there was significantly negative relationship between atmospheric SO2 concentration and acidity of acid rain falling to the protected croplands, The soil pH - value was positively correlated with atmospheric SO2 concentration and acidity of acid rain. Atmospheric S02 deposition and acid rain were the major contributors to the acidification of croplands in Nanchang.
