根据3年来对中国中南部韶山亚热带落叶针叶混交林降水和穿透雨(Tf)的观测结果，对Tf的化学和沉积模式进行了研究和评价。穿透冠层时，Tf化学成分发生显著变化，这可能是由于叶表面的干沉积(DD)和冠层交换所致。盐基阳离子(钙、镁、钾)通量在Tf中显著富集，尤其是K+。冠层年K+交换量∼是DD的12倍，而Ca~(2+)、Mg~(2+)和K+的交换量是DD的4倍。盐基阳离子与弱酸的冠层交换占总淋溶盐基阳离子的28.4%，这是影响盐基阳离子化学的重要因素之一。
The chemistry and deposition pattern in bulk precipitation and throughfall (TF) were examined and evaluated based on the 3-year observations in Shaoshan subtropical deciduous-conifer mixed forest in central-south China. The TF chemistry was notably changed when passing through canopies, which probably was attributed to the dry deposition (DD) on leaf surface and the canopy exchanges. Base cations' (Ca 2+ , Mg 2+ and K + ) fluxes were significantly enriched in TF, in particular for K + . The annual K + canopy exchange was ∼12 times larger than DD, and canopy exchange of Ca 2+ , Mg 2+ and K + was four times as high as the DD. The canopy exchange of base cations in association with weak acid accounted for 28.4 per cent of total leached base cations, which was one of the important factors to modify the TF chemistry.
