摘　　要：腐殖酸类物质调节着全球的碳和氮循环,植物和微生物的生长,重金属的传输,以及土壤结构的稳定等,因此在生态环境中起着至关重要的作用。文章综述了水溶性金属卟啉在土壤腐殖酸的催化氧化聚合反应中的研究进展。土壤腐殖酸的催化聚合可以促进碳固定,减少二氧化碳排放,促进土壤颗粒聚集,提高土壤的物理性状,降低由于侵蚀作用导致的土壤流失,进一步拓展了卟啉在农业和环境保护领域的应用范围。Humic substances are crucial in ecosystems because they regulate the global carbon and nitrogen cycles, the growth of plants and microorganisms, the fate and transport of anthropogenic compounds and metals, and the stabilization of soil structure. A water soluble metal-porphyrin may be easily apply to soil and promote the polymerization of humic molecules. The polymerization of soil humus may potentially facilitate carbon sequestration in soil and reduce it~ C02 emission. Furthermore, an enhanced molecular mass of humic matter would promote soil particles association into larger soil aggregates, thus improving soil physical quality and resistance to soil erosion. The development of a technology based on oxidative polymerization by biomimetic catalysis may be of importance in controlling the properties and reactivity of humic matter for agriculture and environmental applications.
