Quantitative analysis of a stand of Pinus densiflora undergoing succession to Quercus mongolica ssp. crispula : 1. A 31-year record of growth and population dynamics of the canopy trees

摘要: We describe the population dynamics, growth of dominant species and plant biomass production in an ecosystem undergoing succession from Pinus densiflora dominance to Quercus mongolica ssp. crispula dominance. The diameter at breast height (DBH) was recorded for a period 31 years. As DBH increased, tree density decreased. estimated net canopy trees, understory average amount litter. These results suggest that depends on its species’ composition. In order estimate future productivity, it is necessary predict temporal changes
