摘要：

The nutrient content in five forests including Acacia mangium,A.auriculaeformis,Eucalyptus citriodora,Pinus elliotii and Schima superba were studied.The branch and root of different diameter,leaf,trunk and bark were sampled.N,P,K,Na,Ca,Mg,Fe and Mn were analysed.The results showed that the nutrient content had a opposiee relationship with diameter of branch and root.The nutrient content followed a pattern of leaf>branch>root.Very low level of sodium was detected for organs of S.superba and P.Elliotii except for root.The five forests had rather different nutrient contents,though,as legume species,A.mangium and A.auriculaeformis were similar in some elements,especially in N content.
