集材方式作为集材工艺最重要的内容,它的选择决定着伐区的生产方式、作业效率以及生态效益。本文对人力和畜力集材、拖拉机集材、架空索道集材以及空中集材四种常见集材方式进行了介绍,并明确了上述几种集材方式评价因素集合为U={集材效率,生态效益,安全稳定性,经济性}、评价等级集合为V={优,良,中,差}以及各评价因素权重W=(0.35,0.25,0.1,0.3),进而采用加权平均原则对几种集材方式进行了模糊综合评价,得出集材拖拉机集材是相对最优的集材方式。在此基础上,进而提出了一种更适合当下林区生产方式,满足当下集材条件的小型集材拖拉机,并对其进行了模糊评价,得出其为更佳集材方式。
As the most important part of the skidding process, the skidding method determines the production mode, operational efficiency and ecological benefits of the cutting area. In this paper, four kinds of common skidding methods such as human and animal skid, tractor skid, overhead cable skid and air skid are introduced, and the set of evaluation factors of the above skidding methods is defined as U = {Skidding efficiency, Ecological benefits, safety and stability, and economy}, the evaluation grade set is V = {excellent, good, middle and poor}, and the weights W = (0.35,0.25,0.1,0.3) of each evaluation factor, and then use the weighted average principle A comprehensive evaluation of the method of timber collection, the conclusion that the collection of timber tractor skidding is the relative optimal method of timber collection. On this basis, a small-sized tractor that is more suitable for the present forest production mode and meets the current conditions of the current gathering timber is put forward, and its fuzzy evaluation is made. It is concluded that it is a better way of gathering timber.
