| Abstract: | Using the software of SPSS to imitate the growth data of Poplar,which was selected in Flood land of Macheng city,we choose the Quadratic curve as the growth model of DBH and tree age,logistic curve as the growh model of tree height and tree age,then calculate net earnings of Populus SP.for 8 years at the time of felling period. |
| Keywords: | Populus SP growth model economic benefit |
