| 日本の最北端に位置する北海道の十勝地方音更町において，GIS 上に耕地防風林のデータベースを構築することにより，その実態を明らかにし，耕地防風林の減少に歯止めをかけることを目的とした。その結果，音更町の耕地防風林延長は，1995 年が242.3 km，2003 年が255.0 km であり，この8 年間で12.7 km 増加した。耕地防風林樹種別延長割合は，2003 年度においてカラマツ (Larix kaempferi (Lamb.) Carriere) 74.9％，シラカンバ(Betula platyphylla sukatchev var. japonica (Miq.) Hara)9.5％，トドマツ (Abies sachalinensis Fr. Schm.) 3.0％，アカエゾマツ (Picea glehnii (Fr. Schm.) Masters.) 0.5％，その他12.1％ であった。耕地防風林延長を樹高別で比較すると，この8 年間において樹高20 m 以上の耕地防風林は54 km も減少したが，10 m 以下の耕地防風林は7 km しか増加しなかった。耕地防風林の減風効果領域は延長と逆に，この8 年間で1,423 ha も減少した。耕地防風林の減風効果領域と風害発生箇所の関係より，耕地防風林が風害防止に効果を発揮していることが再確認できた。 This research was done to slow the decrease in the use of windbreaks by preparing windbreaks database showing their effectiveness in preventing wind damage in Otofuke, Tokachi... |

| The new large storage facility for the potato reservation was constructed in Yachiyo Region， the agricultural area of the suburbs from Obihiro City in November，2006. The 81 heat pipes were used for the cooling effect in this type storage system. The winter coldness was making the frozen ground on the storage wall by the thermal conduction of working heat pipes. So the cost of the maintenance was spent a little because of the natural energy， such as ice and snow. The floor size of the storage room was 109 in square meters and 60t of potatoes (May Queen) were stored from August to next June commercially. The frozen ground around the heat pipes was created to be 50cm thick during one winter and room temperature was kept under 5℃ until May. The quality of... |
