Abstract:The concentrations of 10 nutrient elements(N,P,SiO_2,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>SiO_2>Zn>NH_4-N>K>NO_3-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,throughfall were K>Ca>NH_4-N>SiO_2>Mg>NO_3-N>Zn>Mn>Fe>P>Cu;Ca>K>Zn>SiO_2>NH_4-N>NO_3-N>Mg>Mn>Fe>P>Cu.The concentrations of SiO_2,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 NH_4-N,K,a lower nutrients enrichment of NO_3-N,P,SiO_2,Ca,Cu,Fe,Zn,Mn in the stemflow was identified in the two items.
