求翻译：兴安落叶松林地土壤有机质含量较高，主要是森林郁闭使林下处于温凉潮湿状态，减缓了枯落物的分解速率，有利于有机质的积累；并且林木在生长的过程中，随着林木的生长，林木根际微生物活性增强，提高了土壤中的蛋白酶、转化酶脲酶、磷酸酶和过氧化酶的活性[16]，促进了土壤中有机物质的降解，增加了土壤有机质的含量，从而改善了林地土壤的物理性质，而且, 经方差分析表明, 各林分的上层土壤有机质含量差异极为显著。是什么意思？

Larch forest soil organic matter content is high, mainly in the forest understory canopy to cool and wet state, slowing the rate of litter decomposition, is conducive to the accumulation of organic matter; and trees in the growth process, with the trees growth, enhance forest rhizosphere microbial a
