Spatial differentiation of urban agricultural ecosystem services—A case study of Xi’an metropolitan zone

Urban Farm DB summary

This study analyzed the spatial differentiation of urban agricultural functions in the Xi'an metropolitan zone, China, using ArcGIS grid technology at a 0.5 km × 0.5 km scale. Findings showed that production-economic function increased from southwest to northeast and from near-suburban to mid-far-suburban plains, while employment function was lower in the Qinling mountainous area than in plains. Cultural-leisure function exhibited a concentric spatial structure, and ecological function decreased from the urban periphery to the center, with severe fragmentation of ecological function value distribution areas.
