| Abstract: | The tree volume table of Cunninghamia lanceolata and Pinus massoniana commercial timber in Mingxi County is complied with the compatibility equation system of stem segmentation binary form factor function taper equation,commercial timber volume equation and stem total volume equation,which not only can fully utilize public published effective tree-measuring information and numercial tables,but also estimate the parameters in the compatibility system in combination with regional resource investigation information,and furthermore,the compiled table errors distribute evenly,absolute and relative errors are small. |
