| Abstract: | In order to increase the precision of the tree height curve graph of the fir and pine plantation in Luoyuan County, the unitary quadratic function of DBH and height of the plantation in Luoyuan was worked out based on the method of comprehensive fitting selection. The electronic table Excel was used as the process for designing and drawing the tree height curve graph. These results have important practical value. |
