摘要
根据伐倒木现场造材样木 ,选择适用的材积比方程编制马尾松人工林一元材种出材率表 ,该表经检验证明适用 .在此基础上 ,结合标准地材料编制了林分出材率表 。
According to sample timbers for conversion on the spot of trees being cut down, suitable equation of volume proportion was chosen to draw up the monobasic log rule of timbers from artificial masson pine (Pinus massoniana Lamb.) forest, proving to be applicable after checking. On this basis, the log rule of standing forest combined with materials from sample plot is worked out, providing scientific basis for production.
