長野県におけるカーボン・オフセットを前提とした未利用林地残材のバイオマスエネルギー利用に関する基礎調査

中部山岳地域の未利用林地残材によるカーボンストック量の算定

抄録

In the production of wood, the trees which are not suitable for lumber such as thin and warped trees are left in the forest as thinnings. The woody biomass energy is considered as one of the way to use the timber offcuts. In this thesis, the abundance of the woody biomass and the amount of carbon stock are calculated according to the survey of the felling records of national and private forest areas, in the Chubu Sangaku area of Nagano prefecture. Following results were obtained by researches.
1. The amount of the timber offcuts were 533,000 m³/5 years in Chubu Sangaku area of Nagano prefecture.
2. The amount of carbon stock of the lumbers were 27,800 t-C/5 years,and the timber offcuts were 100,000 t-C/5years.
