玉潭油藏表层沉积物正烷烃和碳氮同位素

本研究研究了山区储层沉积物中有机碳 （OC） 的来源和移动及其在碳循环中的作用。研究人员发现，大多数 OC 来自外部来源，包括污水 （33.1%）、植物 （27.1%） 和土壤 （19.9%），其中超过 70% 由植物衍生材料组成。农业和城市化等人类活动对 OC 动力学有很大影响，而水库在管理其运输和储存方面起着至关重要的作用。这些发现加深了我们对农业流域碳储量的理解，并为山区水资源管理和生态保护提供了指导。

This study investigated the sources and transport of organic carbon (OC) in reservoir sediments in mountainous areas and their role in the carbon cycle. Researchers found that most OC originates from external sources, including sewage (33.1%), plants (27.1%), and soil (19.9%), with over 70% consisting of plant-derived materials. Human activities such as agriculture and urbanization have a significant impact on OC dynamics, while reservoirs play a crucial role in regulating their transport and storage. These findings enhance our understanding of carbon storage in agricultural watersheds and provide guidance for water resource management and ecological conservation in mountainous regions.
