综述了近几十年来国内外湖泊沉积在全新世尺度上碳酸盐及其同位素、有机质及其同位素的研究进展。主要讨论了湖泊沉积物中碳酸盐含量、δ13Ccarb和δ18Ocarb的环境意义以及二者之间的协同变化,生物成因碳酸盐及其同位素和微量元素等的影响因素及所指示的环境意义,湖泊沉积物中有机质及其同位素和C/N等的影响因素及所指示的气候信息,同时文中还讨论了碳酸盐含量、有机质及其同位素在古气候重建中的应用。
The research progress of carbonates and their isotopes, organic matter and their isotopes in lacustrine deposits at home and abroad over the Holocene are summarized. This paper mainly discusses the environmental significance of carbonate content, δ13Ccarb and δ18Ocarb in lacustrine sediments and the synergetic changes between them, the influencing factors of biogenic carbonate and its isotopes and trace elements and the indicated environmental significance. Sediment organic matter and its isotopes and C / N and other factors and indicate the climate information, while the paper also discusses the carbonate content, organic matter and its isotopes in paleoclimate reconstruction.
