Abstract: Based on the field investigation, the relationship between the amount of earthworm in soils and the age and type of planted forest of Pinus koraiensis is discussed. The author indicates that in order to maintain ecological balance, its necessary to expand mixed coniferous (pinus koraiensis)-broad-leaved forest rather than pure.
