摘要
通过采集山西省天然油松林的根径、胸径样本数据,依据《根径立木材积表编制技术规程》的技术要求,利用数理统计和回归关系建立天然油松林根径—胸径数学模型,同时进行数学模型检验,最后建立根径材积表,以达到支持生产的目的。
Root diameter and DBH data of natural Pinus tabulaeformis forest in Shanxi province were collected. According to the technological demand of Compilation Technical Regulation on Root Diameter Standing Tree Volume Table, mathemat- ical statistics and regression relationship were used to establish Root diameter - DBH mathematical model. Root diameter volume table was established after inspection of mathematical model to support production.
