英文摘要The recovery of community productivity in disturbed temperate forests is affected by fluctuating nutrient environments. How plant growth achieves high biomass accumulation in a limited nutrient environment remains unclear but may be attributed to the flexibility of plant nutrient utilization. Nutrient homeostasis (H) reflects the ability of plant tissues to maintain a relatively constant N and P content under nutrient fluctuations and represents flexible or stable plant nutrient utilization. We aim to reveal the influence of plant nutrient utilization mechanisms on community biomass accumulation after logging. We chose 28 post-logged Korean pine and broad-leaved mixed forests after seven recovery periods (6, 14, 25, 36, 45, and 55 years after logging) with six low-intensity selective logged treatments and one unlogged treatment (100 years after logging). We then estimated the H value of leaf N (HN), leaf P (HP), and leaf N:P ratio (HN:P) and the biomass of 234 plant species with different functional groups, soil nutrient, and species diversity. The leaf HN of 13.19 and the leaf HP of 9.87 reached the maximum at 36 and 45 years after logging, respectively. The HN:P at the community level reached the maximum at 36 years after logging. The robust linear trend between nutrient H and biomass suggests the accumulation of biomass benefits from stable nutrient utilization after logging. Considering the soil nutrient and species diversity, nutrient H showed the major explanation of biomass accumulation in trees, herbs, and whole community. The stable N utilization of tree species accounts for the maximum independent contribution (25.05%) to the community biomass accumulation. Herb species with flexible P utilization had major contribution (37.97%) to herb biomass accumulation. Our study highlights the vital role of high HN in promoting community biomass accumulation in logged forest to assess forest sustainability.
