Abstract
Urban agriculture provides a new strategic idea for solving the problem of urban food demand. The main objective of this study is to develop a spatial model for land suitability evaluation of urban agricultural development under different investment demands (urban agriculture 1.0 and 2.0), based on prospect theory and using GIS and TOPSIS analysis techniques. As a whole, we have developed a land suitability evaluation system for urban agricultural development under different investment needs (urban agriculture 1.0 and 2.0). We constructed a land suitability evaluation system for urban agriculture including ecological environment, social demand and investment cost. The results of the land suitability analysis for urban agriculture 1.0 show that the most suitable area is located in Changle. Compared with urban agriculture 1.0, the most suitable area for urban agriculture 2.0 is in Gulou. It is worth noting that Cangshan ranks second in both scenarios and can be used as a potential solution to balance the ecological environment, social demand and investment cost. Determining appropriate land suitability priorities for urban agriculture will facilitate future agricultural investment management and land use planning.
