| 摘 要： | 欧美杨是河南省的主要用材树种。为准确估测欧美杨的材积,需要编制欧美杨立木材积表。通过外业样地调查,取得1763株样木数据,用1591株建立了立木材积模型,并用172株样木进行了使用精度检验,结果表明,该材积模型适用于河南省,且精度很高。据此编制了河南省欧美杨立木材积表。

| Abstract: | Euro-American Poplar is the main timber tree species in Henau Province.Volume tables need to be constructed in order to evaluate the volume of Euro-American poplar accurately.Date of 1763 sample trees are gotten by field study of sample plots,volume model are constructed and tests of adapt ability are made.The results show that this volume model is suit able to be used in Henau Province and its accuracy is very high.Accordingly,volume tables are constructed. |
