| Abstract: | The biomass and nutrient cycling of mixed plantation of Pinus tabulaeformis and Quercus variabilis were studied, being compared with the pure pine stand and pure oak stand of same age at similar site in Xishan Region,Beijing.The results show that the biomass and productivity 昽f the mixed stand are higher than those of two pure stands,respectively. The nutrient utilization charactor of pine and oak and the suitability of the mixed stand at the site are discussed based on nutrient cycling. |
