实验结果表明，耕作几十年后原森林土壤有机质的含量仍占有主要地位，来源于原始 C3植被的有机碳的比例为 66.7%，但容易矿化的、对植物营养有效的有机质含量较低，这与当地的耕作方式有关，需要加强对植物残留物返回土壤工作的管理。

In this paper, the author disclosed the process of organic carbon conversion in the key stage of carbon cycle in peatlands by means of the analyse to the profile in typical stratums of peatland The purpose of this paper is to reconstruct the environment since late Holocene using the records of molecular fossils in organic compounds and to provide new viewpoints to the research of global change.
