Research on the retention characteristics of nitrogen and phosphorus in urban small-scale aquatic ecosystems
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 urbaniza-tion,nitrogen and phosphorus pollution issues have become increasingly severe.This paper summa-rizes 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 run-off on nitrogen and phosphorus retention,and introduces research methods such as field monito-ring,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 hydrolo-gical characteristics,physicochemical conditions,sediment properties,and biological factors.
