| Research Abstract |
The changes of the stand floor micro meteorological factors in the thinned conifer plantations, were small in the order of large area clear cutting, strip-cutting, and line thinning and single tree felling. In the case of sprit-cutting plantations, the micro meteorological factors of stand floor were equivalent to that of the large area clear cuttings. And, it was suggested by the higher soil water content, the strip-cutting was effective method for stand recruitment. This consideration was supported by favorable successions of the stand floor vegetation in the split-cutting plantations.
