| 英文摘要: |
| In view of the fact that consolidation area for supplementing prime farmland (CASPF) is a new concept proposed in the latest round of general land use planning in China, this paper proposes a new and integrated GIS-based technology for delimiting CASPF. Taking the advantage of the features of CASPF, a comprehensive evaluation indicator system for defining ordinary farmland as CASPF is established in this study, which covers 11 indicators, including slope, land plots connectivity, altitude, surface soil texture, and so on. With the help of the ideal-point method, ordinary farmland plots are sorted according to their evaluation scores in descending order. Based on the space analysis technique of GIS, high-ranking land plots are defined as CASPF reasonably. |
