| Abstract: | The authors proposed a method to estimate forest population timber volume which was based on fixed sample plots set up in the forest resource inventory as the sampling format, GIS as the technique way, and liner regression with topographic factors and forest volume as the method for sampling estimation. Meanwhile discussed the possibility of the method to estimate forest timber volume and presented the formulas calculating unbiased estimation value and variance. |
