Impacts on growth of young trees of Pinus Koraiensis of 6 environmental factors of intensityof sunlight, direct sunlight, thickness of soil humus, neighboring trees, upper canopy species, herbs andshrubs were investigated on young tree of Pinus Koraiensis and 4 neighboring trees which are consideredthe structural unit of the microenvironment. Results indicated that the 6 environmental factors underinvestigation had effects, to various extents, on growth of the young trees. Based on the findings, suitablegrowing conditions for regenerated young tree of Pinus Koraiensis under forest were identified andcorresponding silvicultural measures were proposed for operational practice.
