Abstract

シベリアの北方林地帯を流れるエニセイ川の源流域,中流域,下流域を対象に,地位指数,幹材積及び樹種構成と緯度との関係を,標高や永久凍土などの要因も併せて検討し,明らかにすることを目的とした。カラマツの平均地位指数は高緯度ほど低下し,源流域と下流域では約10mの差があった。幹材積も高緯度域で小さく,下流域は源流域の1/4〜1/3程度まで減少した。樹種構成は,高緯度や高標高地のカラマツが優占した林分から,低緯度のシベリアトウヒの優占度が高い林分まで植生遷移の様々な段階の林分が混在していた。

The purpose of the present study is to analyze the relationship between latitudinal transition and site index, stand volume, as well as tree species composition based on an altitude and natural conditions. We conducted a survey on boreal forest in the upper, middle and lower stream along Yenisei River in Siberia. The average site index of larch declined in high latitude area, and its difference at 100year age stand was approximately 10m between upper and lower stream. The stand volume was small in high latitude area, and it declined by 1/4〜1/3 of the upper stream stand volume in lower stream. With regard to tree species composition, various forests of various succession stages mingled from larch-dominated stands in high latitude or high altitude area to spruce-dominated stands in low latitude area.
