主に環太平洋火山地帯の中から、我国、台湾、ニュージーランド、チリ、メキシコ、米国の火山灰土に関する調査を行った.火山灰土の性質は材料となる火山灰の性質と気候の影響を受けやすい。半乾燥気候下では風化が遅く、炭素貯留機能も弱いが、植物養分の流失は少なく、生物生産機能は比較的高いと見られた。これに対して湿潤気候下では植物養分の流失が速いが、炭素貯留機能が高い。施肥などの養分補給により、生物生産機能は十分改善される。

Investigation of volcanic ash in the Pacific Rim volcanic region, China, Taiwan, China, Russia, Russia, Russia and the United States. The properties of volcanic ash are affected by the material and weather. Under semi-dry conditions, weathering is weak, carbon storage function is weak, plant nutrient loss is small, biological production function is high. Under humid conditions, the loss rate of plant nutrients and the carbon storage function are improved. Fertilization, nutrition and nutrition supply, biological production function is very improved.
