目前我省的森林资源调查,普遍应用以数理统计为理论基础随机抽样的调查方法。但是,计算随机样地的材积,多是用典型样地(标准地)上标准木、计算木编制的材积表查算的。这样以典型样木材积表推算随机样木材积存不存在问题?也就是说,两类样木的干形和树高之间有多大差异?这种差异能给材积计算带来多大误差?直接关系到我省现有的材积表及几 At present, the province’s forest resources survey, the general application of mathematical statistics as the theoretical basis of random sampling survey. However, the calculation of random samples of the volume, mostly in the typical plot (standard) on the standard wood, wood calculation of the volume table for calculation. So using the typical sample of wood volume table to calculate the random sample of wood accumulation does not exist? That is, the two types of sample wood dry and tree height difference between the big difference? This volume calculation can bring much error?
