Inland water carbon (C) sequestration rates play a potentially important role in the balance between C supplies from the atmosphere and associated watersheds and the net demand of primary producers. This study conducts a comprehensive analysis of influencing factors associated with inland water C cycling processes as well as their C sequestration potential and gross primary productivity (GPP). Additionally, we also analyze changes in the balance between C sequestration processes and GPP. Furthermore, this study describes applicable research methods used to quantify C cycling and GPP processes as well as providing corresponding estimates on regional and global scales. Finally, we offer a scientific basis to chronicle how inland water productivity controls exogenous C inputs as well as changes to biological, physical, and chemical factors. Investigations into inland water C sequestration processes under a background of climate warming will become more critical in the future, necessitating the inclusion of different aquatic system component classifications and plant species community types to determine the effects associated with GPP and C dynamic mechanisms within aquatic systems that constitute this diverse water system.

内陆水碳（C）的固存率在大气和相关流域的碳供应与初级生产者的净需求之间的平衡中起着潜在的重要作用。这项研究对与内陆水碳循环过程相关的影响因素及其碳固存潜力和总初级生产力（GPP）进行了全面分析。此外，我们还分析了C隔离过程和GPP之间平衡的变化。此外，本研究描述了可用于量化C循环和GPP过程以及在区域和全球范围内提供相应估计的适用研究方法。最后，我们提供科学依据来记载内陆水生产率如何控制外源碳输入以及生物，物理和化学因素的变化。
