| 摘 要： | 以48株红皮云杉根际圆为材料,以重度力—遗传力的上限为理论依据,经统计分析得出:天然林的重力在0.33-0.52之间,人工林的重力为0.24;据此数据推算出天然林的选择年限在40-60年,人工林的选择年限在15年。

| Abstract: | This article take 48 Koyam a spruce rhizosphere circle as a material,take the specific weight strength-hereditary capacity’s upper limit as the theory basis,obtains after the statistical analysis: Wildwood gravity between 0.33-0.52;The planted forest gravity is 0.24,according to the above the data calculates the wildwood the choice age limit in 40-60 years;Planted forest choice age limit in 15 years. |
