摘　　要：为了能快捷方便掌握变化后的小班森林资源,利用一类清查样地测树资料,编制估测小班蓄积量的数据模型,用“株距法”[1]测得小班林木平均胸径与1/2株距代入方程式,可估测该县市范围内小班现状蓄积量数据。In order to quickly and conveniently grasp the changed sub-compartment forest resources,a data model for estimating the volume of sub-compartment was developed by using the tree measurement data of a kind of inventory sample plot.The average DBH and 1/2 plant spacing measured by“plant spacing method”were substituted into the equation to estimate the current volume data of sub-compartment in the county and city.

关 键 词：一类清查 小班蓄积 数据模型 株距法
