项目摘要

Researches and investigation were carried out at the Yamamoto Forest Company in Kohchi prefecture and Kuma-town in Ehime prefecture in 1990.Main results obtained in this year are as follows.(1) As a result of computerization, 80-100 m per ha for the optimum density of road net-work including forest roads and skidding trails for management forests in Toyoma-town in Miyagi prefecture were obtained. It will be effective density of the road net-work for the logging operations in this area.(2) Study on the index of accessibility in a forest area in order to evaluate the function of road net-work formed by the forest roads were made. Positive study on the correct method for average yarding distance was carried out. The correcting factor 1.4 may be obtained as a appropriate value on normal mountainous conditions.(3) On the productivity of mini-forwarder and mobile tower-yarder for the logging operations, researches were made and the optimum space for yarding operations were obtained. A guide to establish the small scale logging systems including for each operational methods were shown.(4) On the manipulation and the visual ability of operator operating the miniforwarder running on flat land or forest road were studied applying the instrument of the movement of eyeball of the operator. As a result, it was recognized that a rate of the side watching time may be increased as radius of turning of vehicle becomes short.

1990年在高知县山本森林公司和爱媛县熊麻町进行了调查研究。(1)通过计算机计算，得出了宫城县丰山市经营林的林道、集材道等道路网的最佳密度为每公顷80-100米。这将是该地区伐木作业道路网的有效密度。(2)为了评价林区公路所构成的路网功能，对林区可达性指标进行了研究。对平均集材距离的正确计算方法进行了实证研究。校正系数1.4可作为正常山区条件下的适当值。(3)对小型集材车和移动的塔式集材车的生产率进行了研究，得出了集材作业的最佳空间。给出了建立小型测井系统的指南，包括每种操作方法。(4)应用眼球运动测量仪，对小型集材运输车在平地和林区道路上的操作和视觉能力进行了研究。结果，认识到，随着车辆的转弯半径变短，侧视时间的比率可能增加。
