| Research Abstract |
Referring to the SMART model, the organic layr model was developed to describe acidification of forest organic layr. The organic layr model and the modified SMART model were combined to evaluate forest soil acidification more properly. This new model is called two layr model. Considering ecosystem processes concerned to acidification or neutralization, ex. nitrogen mineralization, nitrification, nutrient uptake and creation of organic acid, forest soil acidification was predicted for 100years using the two layr model. Model prediction revealed that nitrogen mineralization rates and nitrification rates had strong effects on forest soil acidification and that organic layr neutralized acid deposition.
The study for the these three years was summarized and published as the book-style report.
