Abstract: The measurement of nutrient elements N, P, SiO₂, K, Ca, Mg, Cu, Fe, Zn and Mn in rainfall, through-fall of canopy and shrub layer, and dripping of herb layer in Cinnamomum camphor plantation showed that the concentrations of test elements in rainfall varied with different month, and their monthly average concentratons decreased in the sequence of Ca＞SiO₂＞Zn＞NH₄-N＞K＞NO₃-N＞Fe＞Mg＞Mn＞P＞Cu. The concentrations of these elements in the through-fall of canopy and shrub layer and in the dripping of herb layer varied in the same way and changed seasonally, most of which were increased. The concentration sequence of the elements in the throughfall of canopy, throughfall of shrub layer, and dripping of herb layer was Ca＞K＞Zn＞SiO₂＞NH₄-N＞NO₃-N＞Mg＞Mn＞Fe＞P＞Cu, Ca＞K＞Zn＞SiO₂＞NH₄-N＞NO₃-N＞Mg＞Fe＞Mn＞P＞Cu, and Ca＞NH₄-N＞K＞SiO₂＞NO₃-N＞Mn＞Mg＞Zn＞Fe＞P＞Cu, respectively. The Fe concentration in the through-fall of canopy and shrub layer as well as the Fe and Zn concentrations in the dripping of herb layer were lower, while the concentrations of other elements were higher than those in the rainfall. Element enrichment except that of NO₃-N, Fe and Zn was stronger in the dripping of herb layer than in the through-fall of canopy and shrub layer.
