Analyzing the soil carbon, nitrogen, and phosphorus content, along with their stoichiometric ratios across different urban-rural gradients, can offer essential insights into enhancing quality sustainable management of urban green space ecosystems. This study focused on Nanchang, China, examining two typical forest types (Pinus massoniana forests Camphora officinarum forests), wetlands (river pond wetlands), as well natural artificial grasslands. It analyzed distribution characteristics organic carbon (SOC), total nitrogen (TN), (TP), “urban-suburban-rural” gradients in surface (0–20 cm) deep (20–40 soil. The results indicated that Pinus forests, rural areas exhibited significantly higher SOC content compared to suburban areas. In TN N:P were greater (p < 0.05). Both layers river showed levels Additionally, wetlands, C:P, N:P, For grasslands, C:N was more than for both layers. areas, TP highly 0.01).
