Judge from the variation of three-dimensional fluorescence spectra with the time of garbage piling in two regions, we can conclude that the longer the pile of garbage, the lower concentration of protein in landfill leachate, the higher the concentration of fulvic acid, which indicate that the protein waste humic substances is easily degradable,in the process, and produce a variety of humus by humification. This has certain significance for the processing of landfill leachate. Key words: landfill leachate; dissolved organic matter; three-d
