AbstractStable organic carbon isotope ratios (ð13C) of bulk organic matter (OM) are commonly used for environmental reconstructions in lacustrine sediment sequences as a tool for reconstructing palaeovegetation. This interpretation is underpinned by the assumption that variations of bulk _13C can discriminate between C3 and C4 plant materials and thus infer palaeoclimate change. However, when organic matters are mainly from C3 and freshwater aquatic plants, this method becomes less effective. Therefore, we have conducted a research to analyse organic molecular compounds of a lacustrine sedimentary seq…
