Burning the forest just once can leave behind enough black carbon to keep the soil fertile for thousands of years.
森林仅仅燃烧一次就能留下足够的黑碳，来保持数千年土壤肥沃。
Land use change is still a major source of carbon dynamics emission due to burning and cultivation, which caused to decline soil organic carbon contents in soils and degrade soil quality.
因烧垦而引起的土地利用变化仍然是碳素释放的主要来源，从而导致了土壤有机碳含量下降和土壤质量退化。
The results show that the great differences between the soil fertility of control burning and that of non-burning are resulted by the different ground clearances.
结果表明：采伐迹地的不同清理方式导致了林地肥力的较大差异。
Fire can also reduce the content of organic matter (SOM) in the surface layer, and it's most obvious in the O and A soil layers at the same year after burning.
火烧会减少湿地土壤的有机质含量，火烧当年湿地土壤草根层与腐殖质层有机质含量下降尤为明显；
