中文摘要：

对樟树人工林生态系统的大气降水、树干茎流、穿透水、林内地表径流、地下径流中N、P、SiO2、K、Ca、Mg、Cu、Fe、Zn、Mn共1O种养分元素含量进行了测定。结果表明：不同月份大气降水养分元素含量不同，各元素各月平均含量按大小排序为Ca〉SiO2〉Zn〉NH4-N〉K〉NO3-N〉Fe〉Mg〉Mn〉P〉Cu。大气降水经过林冠层后，树干茎流、林内穿透水中各养分元素含量变化基本一致，均表现季节动态变化．大多数元素含量增加。树干茎流中各元素含量按大小排序为K〉Ca〉NH4-N〉SiO2〉Mg〉NO3-N〉Zn〉Mn〉Fe〉P〉Cu；林内穿透水中各元素含量按大小排序为Ca〉K〉Zn〉SiO2〉NH4-N〉NO3-N〉Mg〉Mn〉Fe〉P〉Cu。树干茎流中SiO2、Fe、Zn，穿透水中Fe为负淋溶．其余各元素浓度有所增加，在这2项中，除NH4-N、K外，树干茎流中NO3-N、P、SiO2、Ca、Cu、Fe、Zn、Mn养分元素的富集作用均小于穿透水。

英文摘要：

The concentrations of 10 nutrient elements （N, P, SiO2, K, Ca, Mg, Cu, Fe, Zn, Mn）in rainfall, throughfall, stemflow, surface runoff of inside and underground flow were measured in Cinnamomum camphor plantation. The results showed that concentrations of the nutrients in the rainfall varied according to month. The concentration sequence of the nutrient elements in precipitation gone as follows：Ca〉SiO2〉Zn〉NH4-N〉K〉NO3-N〉 Fe〉Mg〉Mn〉P〉Cu. The concentrations of the nutrients in stemflow,throughfall also varied in same way and change seasonally, most of the nutrient elements concentration were increased. The sequence of the nutrient elements contained in stemflow, throughfaU were K 〉Ca〉 NH4- N 〉SiO2 〉 Mg〉 NO3 - N 〉 Zn 〉 Mn 〉Fe〉 P〉 Cu; Ca〉K〉Zn〉SiO2〉NH4- N〉NO3- N 〉Mg〉Mn〉Fe〉P〉Cu. The concentrations of SiO2, Fe, Zn in the stemflow, Fe in the throughfall were lower than those in the rainfall, while the concentrations of other elements are higher. Except to NH3- N, K, a lower nutrients enrichment of NO3- N, P, SiO2, Ca, Cu, Fe, Zn, Mn in the stemflow was identified in the two items.
