    Based on nitrogen(N) nutrient cycling of the rubber (Hevea brasiliensis) plantation of Clone PR107 under different ages(4a~24a)and bymeans of systematical dynamics principle, the models of three compartments including rubber tree, soil and litter were constructed. Meanwhile, the storage, flux and rate of the nitrogen cycling were measured in each compartment.It showed that: 1) the nitrogen storage in the compartment of soil, rubber tree and litter was 3069.61 kg/(hm2·a), 580.22 kg/(hm2·a), 62.94 kg/(hm2·a), respectively.And the trend of the nitrogen storage was increased after declinedin the soil, but keeping increasing in the plant and litter;2)there was a different flux rule in the three compartments.It was that the nutrient absorption, litter decompose and return increased with age growth, while the loss of nitrogen in the rubber latex was related with the production of the rubber latex;3)theflux rate of nitrogen cycling was different in the soil, rubber tree and litter.The absorption coefficient rose with increasing age and ranged from 0.0640~0.1588. In addition, the return and decompose coefficient was 0.1335 and 0.6621, the loss coefficient of rubber latex just was 0.0279, which suggests relatively small loss of nitrogen in the rubber latex. Moreover, the research could provide important basic data for nutrient management of this type of plantation.
