Evaluation of Urban Agricultural Land Use Efficiency based on Urban Agricultural Multi-Functionality—a Case Study of Xi'an City

Urban Farm DB summary

This paper constructed indicators for urban agricultural land use efficiency by incorporating urban agricultural ecosystem service indexes and evaluating their values in Xi'an city using the DEA method, analyzing temporal and spatial changes. Results showed that economic efficiency of agricultural land use gradually increased from 2010 to 2012, reaching 1 in 2011 and 2012, with social and eco-efficiency both in good conditions, indicating increasingly significant urban agriculture service functions. However, economic efficiency decreased spatially from urban core to suburban and rural areas, while social efficiency remained generally high, and eco-efficiency diminished from the city to surrounding counties.
