腐植酸对土壤环境的影响仍然是科学研究需要讨论的话题。本研究目的是调查11种泥炭淤泥质土壤的理化性质与从中分离的腐植酸属性的相关关系。本次测量的土壤参数有：总碳和有机碳、容重、灰分、腐殖化度和吸水指数。选择的腐植酸参数有：280 nm吸光度，465 nm和655 nm、260 nm和655 nm的吸光度比值，元素组成，H/C，O/H，O/C，C/N，氧化程度，羧基和酚基官能团含量。统计分析显示：容重、腐殖化度、吸水指数的升高导致腐植酸参数280 n m吸光度、含氧量、O/H、O/C、氧化度、官能团含量的显著升高。研究还发现土壤属性参数与腐植酸的碳氢含量及H/C比值呈明显负相关。因此，只要测量一些土壤参数，即使没有耗时分离腐植酸，弄清腐植酸的性质也成为可能。%Inlfuence of humic acids on soil environment is still subject of scientiifc discussions. The aim of above stud-ies was to investigate the relationships between selected physicochemical properties of eleven peaty-muck soils and properties of humic acids isolated from these soils. The following parameters were determined for soils:total and or-ganic carbon, density, ash, humiifcation, and the water absorption index. Humic acids were described by:absorbance at 280 nm, absorbance ratios at 465 nm and 665 nm, at 260 nm and 665 nm, elemental composition and atomic ratios:H/C, O/H, O/C, C/N, the degree of internal oxidation, and the content of carboxylic and phenolic groups. Statistical analyses showed that an increase in density, humiifcation, and water absorption indices of soils caused a signiifcant increase in the humic acid parameters:absorbance at 280 nm, the oxygen content, O/H, O/C ratios, internal oxidation degree, and functional groups. Statistically signiifcant negative correlations were found for the same parameters of soils and for the hydrogen and carbon content as well as the H/C ratio of humic acids. The relationships showed that there was a possibil-ity to express the properties of humic acids on the basis of more simple parameters measured for soil and without time-consuming isolation of humic acids.
