Research Abstract

本研究の目的は、リモートセンシングデータから山岳生態系のプロセスを解明するため、生物物理学的、生理学的パラメータを推定し、それらのパラメータを利用して長期的なモニタリングの手法を確立することである。具体的には、(1)リモートセンシングデータによる炭素と水分動態を予測するために欠かせない、葉の生理学的なパラメーター(V_<cmax>など)とその季節変化を予測する、(2) 分光計を利用して個葉および樹冠スケールで分光反射特性を測定し、生物学的なパラメータのアップスケーリングを円滑にする、(3)複雑な地形の山岳地帯でもリモートセンシングデータによる生理学的なパラメータの推定が高い精度を確保する手法を開発する、などが挙げられる。
