| Research Abstract |
Soil warming experiment was conducted in 6 Japanese forests to evaluate long-term effectof soil warming on the soil carbon and nitrogen dynamics. Warming experiment was also conducted to Japanese cypress and cryptomeria saplings to evaluate the effect of warming on the growth. Soil warming enhanced heterotrophic respiration at all of 6 forests, but the increase in the dissolved organic carbon and nitrogen content in the soil water was only observed at a cool-temperate mixed forest. Warming decreased CO2 and H2O exchanges of saplings, but did not change the growth rate within 4-month experimental period.
