摘要
以甘肃省人工云杉林为研究对象,基于收集的680株代表性样木材料,对该区人工云杉林二元材积表的编制进行了研究。结果表明:采用的12种材积备选模型均能较好的拟合材积与胸径、树高的相关关系;通过模型选优,最终确定出11号、12号模型作为甘肃省人工云杉林的二元材积方程式;经适用性检验,林木实际材积与理论材积无显著性差异,材积方程适用于研究区林业生产精度要求,可以为该区人工云杉林林业调查、蓄积估算及科学经营管理提供科学依据。
Taking Picea asperata plantation in Gansu province as the research object,680 representative sample trees of Picea asperata plantation were selected to study the binary volume equation in this area.The results showed that 12 kinds of volume alternative models by used had good fitting effect.Model 11 and Model 12 are finally determined as the binary volume equations of the artificial spruce forest in Gansu province.Through goodness-of-fit test,this volume model precision met the productive requirement,it can provide scientific basis for forestry investigation,accumulation estimation and scientific management of Picea asperata plantation in Gansu province.
