摘要：
The flux of N in broad-leaved Korean pine forest land, Changbai Mountain, Northeast China was studied with thein situ sequential coring technique. The results showed that, in the growing season of 1994 (May to September), net rate of mineralization was 47.96 kg/hm2, plant uptake 28.37 kg/hm2 and leaching losses 20.47 kg/hm2. Net N mineralization rate exceeded plant uptake requirements. On the basis of the N budget, this forest land could be characterized as N saturated though more detailed studies are needed.
