Concentration and distribution of N, P, K, Ca and Mg in a 11 year old artificial Cunninghamia lanceolata stand on a poor soil were studied. The highest concentration of nutrients was found in leaves and fruits, and N and Ca concentrations were higher than those of other nutrients. Accumulation of five nutrients in soil contributed more than 99% of the total in Cunninghamia lanceolata stand ecosystem. The small leaf amount with a lot of attached dead leaves and branches and bad site condition may be responsible for the low yield of Cunninghamia lanceolata stand.
