• The relationship between forest type and site condition in the Tokyo University's Chiba Forest was analyzed using geographic information system. First, the database containing forest conditions and site conditions was constructed. Forest map, stand tables, terrain, roads were stored in this database. Next, the raster layers of forest type and site conditions were created and the areas of each forest type by site condition were calculated by overlaying the layers and totalizing their pixels. The analyses showed the relationship between forest management carried out by the Chiba Forest Office and site conditions in the Chiba Forest.地理情報システムを利用して，東京大学千葉演習林における林型と地況との関係を分析した。最初に，林況および地況に関するデータベースを構築した。このデータベースには森林基本図，森林現況簿，地形，林道を蓄積した。次に，林型や地況のラスタレイヤを生成した。そして，ラスタレイヤをオーバーレイし，各ピクセルを集計して，地況ごとに各林型の面積を求めた。その結果，当演習林が行った施業の結果と地況との関係が明らかとなった。
