The study aimed to evaluate the effects of forest clearcut on nitrogen leaching from the forests developed on volcanic ash soils. Especially this study focused on soil inorganic N and soil organic matter dynamics. In the forest developed on immature volcanic ash soil, the effects of whole watershed scale clearcutting on nitrogen leaching by stream water was relatively smaller than other forest reported previously, probably due to lower soil organic matter contents in immature volcanic ash soil. However surface soil nitrogen transformation pattern of the study site did not greatly differ from other regions. The results may suggest nitrogen transformation pattern of surface soils are not conclusive factors explaining the magnitude of clearcut effects on nitrogen leaching.

本研究旨在评价森林采伐对火山灰土壤上森林氮素淋失的影响。特别是对土壤无机氮和有机质的动态变化进行了研究。在未成熟火山灰土上发育的森林中，整个流域尺度砍伐对溪水氮素淋失的影响相对较小，这可能是由于未成熟火山灰土土壤有机质含量较低所致。但研究区表层土壤氮素转化规律与其他地区差异不大。这一结果可能表明，表层土壤的氮素转化模式并不是解释土壤氮素淋失清除效应大小的决定性因素。
