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.
都市农业为解决城市粮食需求问题提供了一种新的战略思路。本研究的主要目的是基于前景理论，运用地理信息系统（GIS）和逼近理想解排序法（TOPSIS）分析技术，建立一个针对不同投资需求（都市农业1.0和2.0）的都市农业发展土地适宜性评价空间模型。总体而言，我们构建了一个针对不同投资需求（都市农业1.0和2.0）的都市农业发展土地适宜性评价体系。我们构建了一个包括生态环境、社会需求和投资成本的都市农业土地适宜性评价体系。都市农业1.0土地适宜性分析结果表明，最适宜区域位于长乐。与都市农业1.0相比，都市农业2.0的最适宜区域位于鼓楼。值得注意的是，仓山在两种情况下均排名第二，可作为平衡生态环境、社会需求和投资成本的潜在选择。确定都市农业适宜土地的优先顺序将有助于未来的农业投资管理和土地利用规划。
