Study on the regional characteristics of the living environment based on advanced recycling of forest resources in East Asia

在东亚部分地区，已经开发出以下生产技术和施工方法。在中国北部的吉林，传统的原木建造方法是在针叶树50年中期采伐的基础上发展起来的。在日本的平田，基于落叶阔叶树长达100年周期的采伐，发展了Chouna弯梁施工法。在贵州南部的中国，地处暖温带常绿阔叶林中，以中国雪松的采伐为基础，以短期25年为周期，发展出了海兰施工法。在地处热带常绿阔叶林的日本南部岛屿大岛上，以Iju和Mokkoku的采伐为基础，发展了长期百年周期的Hikimonzukuri施工法。我们已经透露，这些森林使用系统正在定义生活方式和村庄位置。

In parts of East Asia, the following production technology and construction method have been developed. In Jilin, Northern China, traditional log construction methods have been developed based on the logging of needle-leaved tree in medium-term 50-year-cycle. In Hida, Japan, Chouna bent beam construction method, have been developed based on the logging of deciduous broad-leaved tree in long-term 100-year-cycle. In Guizhou, Southern China located at warm temperate evergreen broad-leaved forests, hylan construction method have been developed based on the logging of china cedar in short-term 25-year-cycle. In Amami Oshima, Southern Island of Japan located at tropical and evergreen broad-leaved forests, Hikimonzukuri construction method have been developed based on the logging of Iju and Mokkoku in long-term 100-year-cycle. We have revealed that these forest-use-systems are defining lifestyle and village location.
