摘　　要：随着城市化进程的加快,氮磷污染问题日益严重。氮磷在城市小型水生态系统中的滞留特征对水环境质量和生态系统稳定性有重要影响。通过总结国内外关于氮磷在城市小型水生态系统中的滞留特征,分析了氮磷的主要来源及其在水体中的迁移和滞留机制。重点讨论了污水排放、土地利用及地表径流对氮磷滞留的影响,介绍了实地监测、模型模拟、稳定同位素技术等研究方法。研究表明,氮磷在城市小型水生态系统中的滞留受到水文特征、物理化学条件、底泥特性及生物因素等多方面的综合影响。The retention characteristics of nitrogen and phosphorus in urban small-scale water bodies are crucial for water quality and ecosystem stability.With the rapid progress of urbanization,nitrogen and phosphorus pollution issues have become increasingly severe.This paper summarizes domestic and international research on nitrogen and phosphorus retention in small-scale urban water bodies,and analyzes the main sources and mechanisms of nitrogen and phosphorus migration and retention.The paper focuses on the impact of wastewater discharge,land use,and surface runoff on nitrogen and phosphorus retention,and introduces research methods such as field monitoring,model simulations,and stable isotope technology.The findings indicate that nitrogen and phosphorus retention in urban small-scale water bodies is influenced by a combination of hydrological characteristics,physicochemical conditions,sediment properties,and biological factors.
