Abstract

Changes in the delivery of nutrients from land usage and anthropogenic emissions, are known to result in eutrophication in lakes. Both accumulation rates of total organic carbon and total nitrogen concentrations show increasing trends since 1970s, and have increased by as much as 2.5, 2.9 times in Caohu lake sedimentary core. Based on total organic carbon, total nitrogen, the ratios of total organic carbon and total nitrogen , TARHC and OEP, the environmental evolutions have been reconstructed since 1898. From 1898 to 1946 the sedimentary organic matter in Caohu lake was attributed to the mixture of terrestrial plants and aquatic algae. From 1946 to 1972 the source of land plant dominated the organic matter and there may be petroleum pollution. From 1972 to present, the source of algae dominated the organic matter of Caohu lake sediment. It can be concluded that sediment organic matter recorded the beginning of eutrophication at Caohu lake since 1970s.
