摘要
对土壤有机无机复合体结构模型、有机无机复合体与团聚体的关系、有机无机复合体的肥力特征等方面的最新研究成果进行了综合评述。现代测试技术和计算机技术的应用为土壤有机无机复合体的研究提供了新的研究途径,发展形成了腐殖质胶体、有机无机复合体及有机质—异源生物物质复合体的结构模型,在纳米化学水平和三维分子结构模型上重新认识和阐明土壤有机无机复合体的结构和功能;有机无机复合体是土壤改良剂、营养源和重金属或有机有毒污染物过滤器;应在土壤科学、环境科学和生态学中,重视有机物质与矿物质相互作用和结构模型研究,加强土壤有机无机复合体环境化学行为和颗粒迁移动力学的研究。
The intimate complexing of organic matter and minerals in soil is one of the fundamental feature that distinguishes soils from their geological parent materials. This paper reviews the research results on the models of soil organomineral complex, and its fertility characteristics at home and abroad over the years. The modern test techniques and computer techniques have been brought to research on soil organomineral complexes. The molecule structural models of humic colloids, soil organomineral complex and soil organic matterxenobiotics complex have developed. The structure and function of soil organomineral complexes has renewably been understood and illuminated based on nanometer chemistry and three dimension molecule structural model. The organomineral complex is conditioner of soil structure, source and sink of plant nutrients, cultural medium of microbe, and filter of heavy metals or venomous organic pollutants. The importance of interaction of organic matter and mineral, and models of organomineral complex in soil science, environmental science and ecology is emphasized. The research on environmentchemical behavior and transport dynamics of soil organomineral complex will be increased.
