中国北部达里湖DL04岩芯地球化学数据

通过对中国北方达里湖沉积有机质特征的系统研究，重建了末次冰消期间东亚夏季风边缘的千年尺度环境和气候变化。 TOC和TN浓度的同时增加表明陆地有机质和湖泊的养分投入增加，陆地植被和浮游植物生产力的发展与区域温度和降水的增加有关。 C/N比反映了陆地和水生有机物比例的变化。

Through a systematic investigation of the sedimentary organic matter characteristics of Dali Lake in northern China, we reconstructed millennial-scale environmental and climatic changes at the East Asian summer monsoon margin during the last deglaciation. Concurrent increases in total organic carbon (TOC) and total nitrogen (TN) concentrations indicate elevated terrestrial organic matter inputs and nutrient supply to the lake. The development of terrestrial vegetation and phytoplankton productivity is linked to increased regional temperature and precipitation. The C/N ratio reflects variations in the relative proportions of terrestrial and aquatic organic matter.
