Journal of The Japan Forest Engineering Society
The possibility of developing high-graded forest road networks by upgrading existing ones-A widening simulation-based investigation-. J. Jpn. For. Eng. Soc. 37(1): 17 − 26, 2022. Upgrading of existing forest roads is a way of accelerating development of high-graded forest roads. However, the difficulty of upgrading in terms of physicality and economic efficiency differs by conditions of location and structure of existing forest roads. Therefore, it is unclear how amount of development ofdoi:10.18945/jjfes.37.17 fatcat:45z7hi3yvncx3prsp6o4ygicvy
