主要科研成果：

长期从事土壤物理与水文过程研究，主要围绕土壤结构改良与耕地质量提升开展了系统而深入的研究，取得了阶段性的成果：①在土壤结构研究方法方面：创建了稀土元素示踪团聚体周转的新方法，建立了基于CT扫描和图像处理技术的多尺度土壤结构定量化方法；②在土壤结构演变机理与过程方面：创建了土壤结构收缩新模型，提出了土壤收缩类型划分方法，构建了耕作-土壤水-土壤结构三者耦合模型，对结构性收缩成因提出了新观点，指出了耕作压实不改变土壤收缩行为，提出了水耕泥浆化为水稻土裂隙产生的主要机制；③在土壤结构功能与调控方面：揭示了红壤和砂姜黑土等团聚体形成与稳定的关键机制，发现了半干旱/干旱区长期施用厩肥由于Na+累积而导致土壤板结，阐明了土壤结皮对入渗，团聚体对固碳、抗蚀等影响机制。这些研究发展并丰富了土壤物理学方法与理论，为土壤结构改良和农业可持续发展提供了科技支撑。主要研究结果在国际主流土壤学期刊Geoderma、STILL和JoH等发表SCI论文100多篇，参与撰写专著5部，授权专利4项，软件著作权1项。以第一完成人获第15届中国土壤学会科学技术一等奖。
