| description | In the mountainous area of North China, a distinguishing feature of climate is the serious drought of spring and the humidity and high temperature of summer by which the litter production and decomposition of forest litter were strongly characterized. We investigated the dynamic and nutrient characteristics of litter in a 30-year-old mixed stand of Chinese pine (Pinus tabulaeformis Carr.) and deciduous orient oak (Quercus variabilis Bl.) and two comparable pure stands. Oak litterfall peaked in November and pine litterfall in December. The oak stand had the largest annual litterfall (347 g mâ2) and the forest floor mass (950 g mâ2), the mixed stand the second (236 g mâ2 and 634 g mâ2), and the pine stand the least (217 g mâ2 and 615 g mâ2). The nutrient return through litterfall and the storage in forest floor followed corresponding order between three stands. The weight loss of pine and oak foliage litter in first year was 25% and 20%. For senesced pine and oak leaves, the translocation rates of N, P and K were 56â83%. Nutrient concentrations were higher in oak leaf litter than pine needle litter, and the concentration of N and Ca appeared to rise while K concentration decreased in both decomposing litter. |
