Positive Research for Construction of Synthetic Theory on Forestry Production Center Formation Theory and Forestry Systematization Theory

1. 1980年以后，在国内木材萧条的背景下，冈山县的Tsuyama地区和Katsuyama地区作为林业生产中心得到了进一步的发展。原因有很多。第一个是通过复制岐阜县东野生产中心的经验，开始了高质量的标准化木材和干材生产。其他的是不仅新产品在各个锯木厂普及，而且整个地区的成员都系统地专注于新业务，从广泛的地区收集材料原木，并支持木材拍卖市场和木材拍卖市场的信息。因此，市场信息被反馈给锯木厂、伐木企业和森林管理部门。简而言之，在这些拍卖市场的倡议下，木材分配的信息、合理化和附加值的提高鼓励了区域林业的系统化。促进木材生产中心形成和林业系统化两个运动与实际相协调。这种促进在很大程度上依赖和支持木材拍卖市场，这些市场在日本很少出现在山坡生产中心。在木材生产中心的发展过程中，区域森林资源逐渐枯竭。但是，从数量和质量上迅速准备好了后续资源。反映市场信息的造林技术和造林系统迅速提高。因此，这些地区有可能成为大型综合生产中心，既可以生产原木，也可以生产锯材，从苗木护理、造林系统、伐木、伐木到产品销售的所有林业过程都是系统化的。

1. Tsuyama region and Katsuyama region of Okayama pref. Are still more developing as a forestry production center under the domestic timber depression after 1980. There are many reasons. The first is to begin high quality standardized lumber and dry lumber production by copying the experience of Tono production center of Gifu pref. The others are not only thus new production had spread each sawmills, but also whole member of the region had systematizely engrossed in new business, by collecting material logs from wide area and supporting with informations of lumber auction market and log auction market in Katsuyama region. Therefore market infomations are returned back to sawmill, logging business and forest management. In short, regional forestry systematization are encouraged by information, rationalization of timber distribution and raising of added values under the initiatives of these auction markets.2. The two movement that are timber production center formation and forestry systematization are promoted harmony with the reality. This promotion is largely dependent on and supported by the lumber auction markets that stand at hillside production center rarely in Japan.3. In the developing process of timber production center, the regional forest resources were exhausted. But the successional resources are rapidly preparated quantitatively and qualitatively. The silviculture technique and silviculture systematization that are certainly reflected market informations are rapidly improved. Therefore these regions have possibilities to be large synthetic production centers, that are both log production and sawn wood production, with systematization of all process of forestry--from nursing seedling, silviculture system, logging, lumbering and to production marketing.
