Abstract: The content of nutrition, storage and distribution of 5-year-old Pinus radiata young forest plantation were studied in arid valley region in the upper reaches of Minjiang River. The results showed that the P. radiata’s growth and content of nutrition and storages varied greath under different site conditions and climates. The contents of nutritions were different in P. radiata with various height of trunk. The element with the highest content in each apparatus was N. The element Fe were rich in the root system of shrub and herb. The contents of nutrition of P. radiata young forest plantation were 310.47kg/hm2, the contents of nutrition in tree layer, shrub layer、 herb layer and litter layer were 52.25%, 15.25%, 30.84% and 1.66% respectively. There was great diversity of nutrient storages in tree layer under different habitats.
