| 摘 要： | 研究分析伐区调查设计对森林采伐量的影响,主要有三个方面：①伐区调查设计过程对森林采伐量精度的影响,树木胸高确认不同,森林采伐量误差值越大;调查人员测量胸径时所站位置不同,其森林采伐量也不一样;立木所处地形及不同测量工具和调查设计人员,其测量结果都有影响;②枯立木、风倒木对森林采伐量精度的影响;③伐区调查设计规程对森林采伐量精度的影响。总结目前伐区调查设计中存在的问题,寻找提高采伐量精度的方法,为今后伐区的合理的调查设计以及采伐作业提供理论依据。

| Abstract: | In this paper,the impacts of the survey design of forest cutting area on the precision of forest harvesting volume were analyzed from three aspects： the tree height measurement,the standing location of the surveyors,and the terrain of the stands. The influence of dry wood and wind fallen trees as well as the cutting area survey design procedures on the precision of forest harvesting volume were investigated. The problems existed in the design of cutting area investigation were summarized and the ways of improving the precision of cutting volume were identified,which provide references for the reasonable design of cutting area and forest harvesting operation in the future. |
