摘要
在福建南平对降水酸度及化学成份进行了为期一年的定位监测．结果表明，降水通过杉木人工林截留后，其ｐＨ值降低，伴随离子浓度的增加，电导率也明显上升，尤以树干茎流为显著．降水的ｐＨ值、电导率和主要离子浓度也表现出一定的季节变化．
The located monitoring for acidity and chemistry of precipitation was carried out at Xiqin Experimental Farm in Nanping over one-year-period. The acidity, concentrations of chemical components, and electrical conductivity of intercepted precipitation by Chinese fir plantation especially stemflow, were consistently much greater than open rainfall, and showed seasonal patterns.
