%X The accumulation and biological cycle of N and P nutrients in Pinus taiwanensiscommunity in Wuyi mountains, Fujian Province, were studied. The results were as follows: 1) The amounts of N and P in the standing crop of this community were 925.844 kg hm2 and 45.981 kg hm-2, respectively, in which the amounts of the two nutrients in the above- ground biomass were 719.438 kg hm2 for N and 35.534 kg hm2 for P, and in the underground biomass were 206.406 kg hm2 for N and 10.447 kg hm2 for P. 2) In biological cycle of N and P of this stand, the annual vegetation mineral uptakes amounted to 65.344 kg hm2 and 2.627 kg hm-2, respectively. The retention of N and P were 37.019 kg hm2 and 1.695 kg hm-2, and their return being 28.325 kg hm2 and 0.932 kg hm-2, respectively. 3) The enrichment ratios of both N (1.324) and P (1.083) were larger than l, demonstrating the two nutrients being continuously accumulated in the community.
