计算拖拉机平均集材距离,是伐区工程设计中必不可少的内容,对确定拖拉机集材效率、配备油锯及拖拉机数量都有着密切的关系。在实行采集作业的经济管理、计算单位集材成本方面起到重要作用。近几年来,伐区地形越来越复杂,平面图形状不一,但基本上可以近似看作由三种类型组成的,长方形、三角形和扇形。下面就这三种比较规则集材小号图形的平均集材距离的计算阐述如下:
Calculating the average tractor tractor distance is an essential part of the cutting area engineering design and is closely related to determining the tractor skidding efficiency and the number of tractors equipped with chainsaws and tractors. It plays an important role in the economic management of collection operations and in the calculation of the unit cost of timber. In recent years, cutting terrain has become more and more complex, plan shapes vary, but basically can be approximated as consisting of three types, rectangular, triangular and fan-shaped. The following is the calculation of the average sliver distance for these three comparative truncation truncates:
