BASIC STUDY ON CONSERVATION AND UTILIZATION OF PRIVETE BROAD-LEAVED FORESTS

调查了以宫崎县为主的南部Kyuhyu的硬木使用趋势。硬木已被加工成生活中使用的各种产品。然而，天然阔叶林的大材、优质材的减少，导致木材加工原料的短缺。此外，通过实地调查和对私有阔叶林所有者的询问，对九州岛3个县的私有阔叶林经营、采伐和营林工作的对象进行了调查。这些年来一直在进行采伐和造林工作，此外，所有者对阔叶林与自然保护之间的关系感兴趣。这一趋势今后将继续下去。结果表明，从自然保护、林地保护和流域保护的角度出发，应重点经营阔叶林，生产优质香菇原料材、纸浆材和名贵用材林。

The trend of the use of hardwood was surveyed in Southern Kyuhyu mainly in Miyazaki Prefecture. Hardwoods have been processed to various products used in life. However the decrease of the natural borad-leaved forests consists of large and high quality timber has brought out the shortage of materials suitable for wood processing. In aadition, objects of management, harvesting and silvicultural works on private broad-leaved forests in three prefectures in Kyushu island were surveyed by field work and inquiring from private broad-leaved forest owners. The harvesting and silvicultural works have been practiced in these years and in addition owners are interested in the relationship between broad-leaved forests and nature conservation. This trend will continue in future. These results indicate that the broad-leaved forests should be managed to produce material wood for shiitake mushroom, pulp wood and expensive timber wood with high quality considering nature conservation, forest land conservation and watershed protection.
