As results of the surveys of the Cryptomelia japonica forests at Yashino, Kasugayama, and Murooji in Nara prefecture, of some kinds of forests at Oneyama forest park in Gunma prefecture, of the Chamaecyparis obtusa forests at Akasawa forest park in Nagano prefecture, and of Pinus densiflora and Chamaecyparis obtusa forests at Kamiina County in Nagano prefecture, we have revealed their forest structures.And, at Ise shrine forest, we have interviewed the person in charge about the policy of forest management.And then, we have analyzed the forest structures of 5 forests at Kamiina County, including man-made forest where the management have been stopped, managed forest, and scenic beauty forest.As a conclusion drawn from above-mentioned results, we can make following policies about the scenic thinning aiming for great trees forest.1. Improve overstocked stand which inhibits plantation forestry in man-made forest where the management have been stopped.2. Consider as goal great trees forest which consists of the present trees in man-made forest where the management have been stopped and in managed forest.3. Maintain the stratification of forest and its diversity, considering the balance of upper story and under story to eternal forest regeneration.

通过对奈良县矢野、春日山、室小路的日本柳杉林、群马县根山森林公园的几种森林、长野县赤泽森林公园的钝叶山慈菇林、长野县神名县的赤松林和钝叶山慈菇林的调查，揭示了它们的森林结构。在此基础上，对神名县停止经营的人工林、经营林、风景林等5种森林的森林结构进行了分析，得出了以大树林为对象的风景林间伐的对策。在已停止经营的人工林中，对抑制种植园林发展的郁闭林分进行改造.以停止经营的人工林和经营林中的现存树木组成的大树林为目标.保持森林的层次性和多样性，考虑上层与下层的平衡，实现森林的永续更新。
