THE HICH GROWTH OF PINUS TABULA EFORMIS CARR IN THE NONATURAL FOREST IN THE SECONDARY FOREST REGION OF THE DAQING MOUNTAIN |
| |
| Abstract: | The paper, through the investigation and research on the high growth?ituation of pinus tabulaeformis carr in the nonnatural forest in the secondaryforest region (about 20 years old) of the Daqing mountain region, makesa further study on the qualitative relationship between the natural situationof the area and high growth of pinus tabulaeformis carr. At rhe same time,by using the methord of grey mathematics, a model of a high growth GM(n) has been set up, which can be both used to describe the regularityof the high growth of pinus tabulaeformis carr and make short-term forcasts. |
