| Abstract: |
| Taking Larix kaempferi plantation in Western Hubei Province as the research object,670 representative sample trees of L. kaempferi plantation were selected to study the binary volume table"" compiling in this area. The results showed that 12 kinds of volume alternative models by used had good fitting effect. Model 3 was determined as the optimal model in study area with multiple models optimum seeking method. Through goodness-of-fit test, this volume model precision met the productive requirement, it could be provide scientific basis for forestry investigation, accumulation estimation and scientific management of L. kaempferi plantation in Western Hubei Province. |
