土壤碳库动态平衡决定土壤-大气系统中碳的源/汇转变，其消长变化一方面影响土壤肥力，另一方面强烈影响大气CO_2浓度的变化。本书基于农田尺度的黑土生态系统长期定位试验，主要研究土地利用变化及不同施肥管理措施对土壤有机质碳、氮消长动态的影响，土壤团聚体和密度组分中有机碳、氮的分布特征及物理性保护机制；研究土壤碳排放特征及经过土壤-植物-大气系统碳截存，揭示黑土碳库的固碳容量及固碳机制以及土壤-植物-大气系统的碳收支平衡，为阐明黑土有机碳的肥力特性和环境行为提供理论依据。本书的特点是选择我国珍贵的土壤资源—黑土作为研究对象，黑土的开发与利用关系到国家与区域的粮食安全。有关黑土有机碳的研究已取得许多重要成果，但是对于黑土作为碳储存库的研究才刚起步，因此，本书的研究内容具有区域的独特性和科学前瞻性。
