Rapid city expansion and intensive human activities have remarkably affected nitrogen flow, leading to increasingly intricate spatial heterogeneity of flow. Focused on the temporal characteristics flow at certain scales, existing research has missed comprehensive grid-scale models for To address this gap, study develops a model by incorporating both natural anthropic processes. Taking Xiamen as its case, utilizes grid technology analysis build detailed scale. The results in 2015 revealed that hotspots input were primarily located surrounding areas outside east Xiamen, with maximum reaching 20.07 × 104 kg/ha. However, load atmosphere concentrated urban center (i.e., Island) nearby sea areas. outputs can reach 18.32 kg/ha, which is 18 times total output water environment. Additionally, it was found significant gradient correlation exists between population density. These findings provide support low-nitrogen planning emission reduction policymaking.
