| 摘 要： | 研究区酸雨出现的频率平均为20．65％，常绿阔叶林冠层穿透水和树干流均使降雨的pH值发生变化，总径流水和地表径流水的pH值则是常绿阔叶林的低于荒草疏林地，林内土壤酸性较林外土壤强，且表层土要酸于下属土。

| Abstract: | Averaged emergency frequency of acid rain in the research area was 20. 65%. The water from crown canopy of evergreen broad-leaf forest and trunck made pH value of precipication change. pH vaines of total runoff and surface runoff were higher than those in opening. Soil acidity in forest was higher than that outside forest and Surface soil was acider than lower soils. |
