在大面积森林资源清查中,采用分层抽样调查方法,无论在精度上还是在速度上,都显示了很大优越性。为了摸索分层抽样对小面积次生林资源清查的适用性,在省林科所的具体帮助下,我们在本场冰沟营林区长梁沟作业区进行了初步赏试,平均蓄积量抽样相对误差限±9.9％,达到了精度要求。 In large-scale forest inventory, stratified sampling method, both in accuracy and speed, have shown great superiority. In order to explore the applicability of stratified sampling to the inventory of small-area secondary forest resources, with the help of the provincial forestry institute, we conducted a preliminary rehearsal test in the Changliangou work area of ​​Binggouying Forest Zone. The average volume of samples collected was relatively Error limit ± 9.9%, reached the accuracy requirements.
