Description

　天竜林業の展開過程は，その造林地形成期においては，焼畑造林（山作り林業）として展開したといってよい．それは，耕作複合の一環として造林が進展していったことを意味する．
　しかし，昭和に入り焼畑造林（山作り林業）の衰退とともに，独立の造林方式が徐々に確立し，純林方式に移行していった．この過程で植栽本数の増加をみたが，間伐の一般化とともに植栽本数の減少が進み，伐期も長期化の傾向をたどる．
　純林・独立の造林方式は，労働力を育林労働と遊離させる方向をうながし，昭和30年代後半に至ると，労働カの組織化対策に迫られるようになる．森林組合による労働カの組織化がそれである．
　今後，林業生産を安定的に維持し，労働力の安定就労を確保していくためには，新たな生産の複合，産業のコンプレックス化による複層産業構造（ポリカルチャー）をどう形成させるかにかかっているといえよう．
