在分析赛里木湖湖泊沉积物中氮含量(TN)、有机碳含量(TOC)及其碳同位素(δ~(13)C_(org))以及色素等指标的变化特征的基础上,结合沉积物中有机指标的环境意义的探讨,揭示了新疆赛里木湖湖泊沉积物中有机质所蕴含的环境信息.赛里木湖沉积物中总有机碳含量、总氮含量的变化反映了流域初级生产力的变化,沉积物色素变化是有机质保存条件的指标,间接指示了湖泊-流域水热配置环境.有机碳同位素(δ~(13)C_(org))反映了湖泊内外源的混合信息.结合有序样品聚类分析方法,可以将赛里木湖近代环境划分为四大发展阶段:1、各有机指标相对稳定;2、各有机指标明显波动;3、各有机指标显著增加;4、各有机指标快速增加.
Based on the analysis of the change characteristics of nitrogen (TN), organic carbon (TOC), carbon isotope (δ ~ (13) C_ (org)) and pigments in Sediment sediments, The discussion of the environmental significance of the organic indicators in the sediments revealed the environmental information contained in the organic matter in the sediments of Lake Limong Lake in Xinjiang.The changes of total organic carbon and total nitrogen in Sediment Lake sediments reflected the primary productivity , The change of sediment pigments is an indicator of the preservation conditions of the organic matter and indirectly indicates the hydrothermal environment in the lake-basin.The organic carbon isotope (δ ~ (13) C_ (org)) reflects the mixed information inside and outside the lake, The orderly cluster analysis method can divide the modern environment of Sailimu Lake into four stages of development: 1, the organic indicators are relatively stable; 2, the organic indicators are obviously fluctuating; 3, the organic indicators are significantly increased; 4, Indicators increased rapidly.
