Outline of Research at the Start

東南アジア島嶼部には熱帯泥炭地が広がり,泥炭林と共存して膨大な量の土壌有機物(泥炭)を蓄積してきた。しかし近年,オイルパーム農園の開発・拡大による森林伐採と乾燥化により,泥炭の好気的分解(CO2排出)が促進されている。本研究では,農園を含む泥炭生態系に分布する観測サイトをネットワーク化し,温室効果気体(GHG)とエネルギーのフラックス(大気-生態系間の交換量),気象・土壌環境などに関するデータベースを構築し,衛星リモートセンシングや生態系モデリング,気候シミュレーションを活用して,熱帯泥炭林のオイルパーム農園への転換が炭素蓄積量および炭素・エネルギー収支に与える影響を解明する。

Outline of Final Research Achievements

Tropical peatlands in Southeast Asia have accumulated enormous amounts of soil carbon as peat, but the expansion of oil palm plantations with drainage has accelerated oxidative decomposition of peat (CO2 emissions), increasing the vulnerability of peat carbon. In this study, we used field observations, satellite remote sensing, and regional climate model data, as well as synthesis analysis of observation data from 11 tower sites, to elucidate the impact of large-scale land use change and droughts caused by El Nino events on the greenhouse gas budget in tropical peatlands.

Academic Significance and Societal Importance of the Research Achievements

現地観測によって熱帯泥炭地の温室効果気体および泥炭炭素の動態に及ぼす撹乱の影響を定量化したこと,また,統合解析によって降水量・地下水位・温室効果気体のフラックスの間の関係をモデル化したことは,関連研究分野の発展に寄与する成果である。また,温室効果気体の収支の時空間変動を広域で定量化する実用的な手法を開発したことは,気候変動・土地利用変化の影響や環境修復の効果の定量化のために有効であり,社会的意義は高いといえる。
