Effects of thinning on soil organic matter dynamics and carbon budget of artificial forests

以日本典型人工林日本落叶松、日本落叶松和日本柳杉为研究对象，研究了间伐对其固碳和收支的影响。结果表明，日本林业和渔业省为防止青海变暖而推动的人工林间伐对碳收支没有明显的负面影响，碳收支是由相关森林的碳固定排放量减去碳释放量而确定的。也就是说，相对于固碳而言，碳释放几乎没有增加。

On the representative artificial forests in Japan including Larix kaempferi, Chamaecyparis obtsusa and Cryptomeria japonica the effects of thinning on the carbon fixation and budget of those forests were investigated. As the results obtained thinning of artificial forests, as promoted by the Ministry of forestry and Fisheries, Japan, for the sake of the prevention of glaobal warming, had no apparent negative effects on the carbon budget that was determeined by the substraction of the amounts of carbon release from those of carbon fixation by the relevant forests. that is, little increase in carbon release relative to carbon fixation was observed.
