摘要
对杉木人工林的单位面积蓄积量、平均胸径、平均树高以及株数的生长模型采用民理查德方程来进行计算,并结合了相关公式编制了一份收获表,收获表在经检验后表明据有一定的科学依据,非常适宜,对林分生长收获的预估和小班资源数据更新有着非常重要的作用,文中最后给出了应用经验收获表进行生长收获预估的实例。
Cunninghamia lanceolata was established the: select Richard equation,then the average tree height volume per unit area and average DBH and the growth of the number of models, combined with relevant formula,then the experience harvest table of cunninghamia lanceolata was compiled the test has proved that this table is used,can be used for forest growth and harvest estimates for updating subcompartment resources data and in the end,then the experience harvest table is given for instance of harvest forecasts for growth.
