研究テーマ

東南アジア熱帯雨林・熱帯季節林の熱・水・炭素循環に関する研究


学位論文

卒業論文:「樹冠葉面温度の実態とその形成機構」
東京大学農学部附属千葉演習林内の試験地においてスギを対象木とし、熱電対を用いて葉気温差(葉面温度と気温の差)及び葉面温度を直接測定しました。さらに、同対象木において測定された樹液流の観測値及び微気象観測値から、Penman-Monteith式を土台としたビッグリーフモデルによって葉気温差及び葉面温度を算出しました。この計算値と観測値とを比較しました。


修士論文:「常緑熱帯モンスーン林における蒸発散の季節変化と年変動」


博士論文:「Studies on seasonal and inter-annual variations in transpiration and its controlling factors of a tropical deciduous forest in northern Thailand」
