摘  要:
研究生命有机物质的腐殖化过程是了解碳的生物化学循环所必不可少的。本研究的主要目的是分析泥炭性质、泥炭腐植酸与泥炭腐殖化度三者之间的关系。对两个雨养泥炭沼泽的泥炭剖面各层中提取的腐植酸样品进行了分析,并对泥炭年龄、分解度、腐殖化度、植物构成、泥炭腐植酸性质(元素和有效成分)进行了研究。结果发现,泥炭腐植酸的组成受造炭生命有机物质前体的组成影响较小,对造炭生物性质多样性的研究要比对泥炭性质多样性的研究更有意义,由此可以揭示腐殖化过程对泥炭性质的主导性作用。

摘  要:
Studies of the living organic matter humification process are essential for understanding the carbon biogeo- chemical cycle. The aim of this study is to analyze relations between the properties of peat, peat humic acids and peat humification degree. The analysis has been done on samples of humic substances extracted from peat profiles in two ombrotrophic bogs and relations between peat age, decomposition and humification degree, botanical composition and properties of peat humic acids (elemental, functional composition) were studied. The found variability of peat properties is less significant than differences in the properties of peat-forming living matter, thus revealing the dominant impact of humification process on the properties of peat. Correspondingly, composition of peat humic acids is little affected by differ-ences in the composition of precursor living organic material.
