| 摘 要： | 通过一年的定点对比监测表明，树干茎流的酸度明显地高于林外雨和林内雨的酸度，高污染源较近的西芹监测场的降水酸度普遍比污染源较远的福建林学院监测场的高．降水酸度影响了林下土壤的性质．林下土壤交换性酸度随降水酸度的提高而增加，而土壤交换性盐基离子浓度和Ｃａ２＋／Ａｌ３＋则相应下降，土壤有效磷的含量也略有下降．

| Abstract: | Acidity of stemflow was much greater than that of open rainfall and throughfall at two located monitoring slies at varyng distances from sulphur dioxide sources.Emissions of sulphur dioxide appeard to have acidifying effect on open rainfall,throughfall,stemflow and soil solution at Xiqin site mear major sources.Resulting effects on soil chemistry included elevated exchangeable bases and Ca2+/Al3+ ratio,and slightly decreasd available phosphorus. |
