采用高强度（平均离子强下10年、20年、30年雨量）模拟酸雨淋滤珠江三角洲地区的潮土,用重铬酸钾滴定法测定淋滤后土壤的有机质含量。研究表明：高强度模拟酸雨对土壤有机质含量的影响不大。各层土有机质含量变化最大的为下降13.04%,最小的为-1.33%。

The moisture soil in Pearl Rivet Delta was leached by high intensity（ten,twenty and thirty years rainfall amount） simulated acid rain and the content of soil organic matter was determined by titration with potassium dichromate.The study showed that the high intensity simulated acid rain had little influence on the change of soil organic matter content.The maximum percent of decrement of soil organic matter content was 13.04 %,and the minimum was-1.33 %.
