7Gm〓 in the 20 yr forest, 1139. 8gm〓 in the 80 yr forest and 912. 4 gm〓 in the climax forest, respectively. However, along with forest succession, the dominant tree species fine root annual production increases, whereas other arboreal and grass fine root annual production decreases.

白桦山杨幼林、白桦山杨成熟林与原始阔叶红松林中，细根年生长量分别为712.7gm〓、1139.8gm〓和912.4gm〓；但是，随着演替的进行，林地主要树种细根的年生产量会逐渐增加，其它木本和草本细根的年生产量则逐渐降低。

In the 20 yr forest, 304. 6gm〓 C and 11. 6gm〓 N are inputted to the soil. In the 80 yr forest, 502. 3gm〓 C and 17. 2gm〓 N are inputted to the soil. In the climax forest, 430.3gm〓 C and 11. 9gm〓 N are inputted to the soil. Along with forest succession, the C inputted to the soil B layer by fine root increases because of the deepening of root depth distribution.
