| 摘 要： | 本文对东北和内蒙林区伐区常年林道与冻板道比例优化问题进行了研究。结果表明,伐区综合林道合理密度值只与伐区冬季作业条件有关,而与夏季作业条件无关;伐区常年林道和冻板道占综合林道的合理比重不仅与表征冬、夏季作业的自然条件参数、设备参数和作业人员参数有关,而且还与木材生产组织程度有关。理论分析和实例计算结果表明,提高木材生产组织的优化程度,对于降低伐区作业费用有着重要意义。

| Abstract: | After analysing the operation systems in cutting area in the North of China, the author presents a non-linear programming model, Basing on the forest operation parameters, such as cutting area terrain parameters, operation equipment parameters, operation worker parameters and the parameters of whole forest harvesting operation organization, we can use this model to determine the optimal proportion between the perennial road and seasonal road in cutting area, It is proved that the optimal density of comprehensive road in cutting area is independent of the operation conditions in summer and the optimal proportion of road composition in cutting area depends all the operation conditions in both summer and winter. |
