The relative fluorescence, normalised on dissolved organic carbon (DOC), and a humification index, based on the location of the fluorescence emission spectra, were used to investigate the possible sources of the increase in dissolved organic matter (DOM) when a soil is dried. From these 2 parameters it could be seen that air drying resulted in a minor increase of more humified material in DOM while the effect of oven drying was mainly due to cell lysis.
以溶解有机碳（DOC）归一化后的相对荧光以及基于荧光发射光谱位置的腐殖化指数，用于研究土壤干燥时溶解有机物（DOM）增加的可能来源。从这两个参数可以看出，风干导致DOM中腐殖化程度更高的物质略有增加，而烘干的影响主要是由于细胞裂解。
