Effect of thinning for the stand floor micro meteorology and plant communities in conifer plantations

间伐后人工针叶林林分地面微气象因子的变化从大到小依次为大面积皆伐、带状采伐、线间伐和单木采伐。喷伐人工林林分地面微气象因子与大面积皆伐林分相当。在土壤含水量较高的情况下，带状采伐是林分更新的有效方法。这种考虑得到了支持的林分地面植被的有利演替劈砍人工林。

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.
