导言森林的疏伐作业增加成本与技术复杂性,因此需要用更好的方法来计划和监控这些工作。然而计划采伐所需要的信息,常常不是用传统的森林调查来收集的。例如,随着伐木集材机的出现,就产生关于根径信息的需要。可是伐木集材机限制了剪切和积存器的能力。这样,为了设计机械化的选择式疏 Introduction Forest clearing operations add cost and technical complexity and therefore require better ways to plan and monitor these efforts. However, the information needed to plan logging is often not collected using traditional forest surveys. For example, with the advent of logging skidders, there is a need for information about root diameter. However, lumber skidders limit the ability to shear and accumulate. In this way, in order to design mechanized alternative sparse
