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.

在稀薄的针叶树种植园中，支架地板微气象因素的变化在大面积切割，切割，剥离以及线变薄和单树砍伐的顺序上很小。在割草林的情况下，支架地板的微气象因子相当于大面积的透明插条。而且，这是由较高的土壤含水量提出的，剥离是募集的有效方法。这种考虑得到了分裂种植园中支架地板植被的有利继承的支持。
