Abstract:
In recent years,the application of n-alkanes carbon molecules and carbon isotopic distribution has been one of the hot issues in global change research in the field of environment. This paper summarized the achievements of domestic and foreign utilized the n-alkanes and δ13C in biological input identification,vegetation type judgment and recovery and reconstruction of paleovegetation and paleoclimate. The climate and environment changes in Lake Shijiu were discussed using n-alkanes and δ13 C. The results show that the distribution of n-alkanes compounds in Shijiu Lake sediments is mainly derived from terrestrial higher vegetations,the most abundant components are nC27 ~ nC31 ,which show a significant odd-even predominance. Besides,from the bottom to surface,the relative content of long chain n-alkanes in the sediments was decreased while the short chain n-alkanes was increased. It can be inferred that terrestrial higher vegetations in this basin were gradually decreased while algae and other macrophytes were gradually increased over the past century. This indicates that eutrophication phenomenon has highlighted and ecological environment is becoming worse in the Basin of Shijiu Lake recently.
