Plot-sampling method was used to determine the influence of different site conditions on the plants and soil organic nutrients and carbon pools of the natural P.tabulaeformis and artificial P. tabulaeformis in Ziwuling region. With the natural P. tabulaeformis community as the control standard, artificial P. tabulaeformis communities. Under different site conditions were investigated to study their soil nitrogen pools, soil carbon pools and plant nutrient pools, plant carbon pools. The study showed that in the region the average C, N and P contents of P. tabulaeformis needles were (4995±6375) mg/g, (8.53±0.50) mg/g and (0.94±0.64) mg/g, respectively. The C contents of plant leaves decreased in the order of natural forest on sunny slope> natural forest on shade slope> plantation on shade slope> plantation on sunny slopes. The N and P content of plantation leaves in sunny slopes were obviously higher than that of the natural forest in sunny slope. There were significant differences in leaf C/N, C/P, N, P and N/P among the four types of P. tabulaeformis communities under different site conditions. The leaf C contents were negatively correlated with the leaf N and P contents. And the leaf N contents were observably positively correlated with the leaf P contents. There was no significant difference in C and N content in 40-60 cm soil, but in the other soil layers, the C and N contents in the plantation soil was significantly higher than those in the soil of the natural forest. The C and N content of the plantation on sunny slope soil was significantly higher than that on shade slope soil. Soil C both in 0-20 cm soil and 20-40 cm soil were positively correlated with soil N, and plant N and P. The leaf nutrient content were the maximum in the plantation sunny slope, the soil communities in this region were the greatest soil nutrient pools and carbon pools. The obvious correlation of soil C and N with the C，N and P in P. tabulaeformis leaves showed that there were interactive relations between P. tabulaeformis and soil.
