Soil dissolved organic carbon (DOC) is a primary form of labile carbon in terrestrial ecosystems, and therefore plays a vital role in soil carbon cycling. This study aims to quantify the budgets of soil DOC at biome and global levels and to examine the variations in soil DOC and their environmental controls.

陆地生态系统中土壤溶解的有机碳：全球预算，空间分布和控制

土壤溶解的有机碳（DOC）是陆地生态系统中不稳定碳的主要形式，因此在土壤碳循环中起着至关重要的作用。这项研究旨在量化生物群落和全球范围内土壤DOC的预算，并研究土壤DOC及其环境控制的变化。
