| Abstract: | The density of Poplar-Birch forest was studied by using the method of location observation in fixed plots and investigation in temperate plots. The mathematical models of maximum density. the best density and minimum density for Poplar-Birch forest were obtained. It is showed that the best density and minimum density are 0. 70 and 0. 55 respectively for Poplar-Birch forest. |
| Keywords: | Poplar-Birch forest Management density Mathematical model |
