This article uses fixation swatch founding for second - class investigation to obtain character of 207 sample trees, by which mathematics model of ground diameter volume table of chinese fir were deduced by regressing and imitating with five of equations respectively, and used unitary and binary volume tables of timber respectively to reckon an unitary ground diameter volume table, then compared the two ground diameter volume tables, so that a ground diameter volume table of chinese fir in yanping district was compilated to satisfy essentially the precision demand of forestry production, and to serve forestry production
摘要利用二類調查布設的固定樣地，收集207株樣木調查資料，分別採用5個方程進行回歸擬合，選出杉木人工林地徑材積表的方程模型，利用一元材積表和二元材積表導算編制一元地徑材積表，並進行比較，結果表明二元材積表導算地徑材積表的方法精度較高，基本滿足林業生產所需精度要求，可以提供林業生產服務。 -
