红旗林场杉木地径一元材积及出材率表的编制

摘要

利用回归方程建立杉木地径与胸径、树高曲线方程,并结合福建省杉木二元材积公式和出材率表编制了红旗林场杉木地径一元材积表和出材率表,经检验,其精度符合要求,适合红旗林场杉木林分使用.%Combining with the duality volume equation and the outturn table of Chinese fir in Fujian province, the curvilinear equations between basal diameter, DBH and tree height were established by applying regression equation. One- variable volume table and outturn table of stand of Chinese fir in Hongqi Forest Farm were constructed. The results of examination show that the precision of the tables are in accordance with related requirements and can be used on Chinese fir planted in Hongqi Forest Farm.
