The selection of reclaimed land parcels based on The Third National Land Resources Survey
The arable land area is declining sharply in recent years due to the problems of"non-agricul-ture"and"non-grain conversion"for arable land in China,as well as the increasingly intensed"forest(garden)and grain land competition"in land using.Therefore,a precisely selecting method for suitable reclaimed land from ready-to-be recoverable land and engineering recoverable land types is put forward in this paper to ensure that the red line for basic arable land remains unchanged by using the data from The Third National Land Resources Survey.It is helpful to increase arable land area and to get better balance between social and engineering benefits by using the ArcGIS software platform,and by comprehensively considering the optimal social and engineering benefits as the guiding rules.This method can be used to quickly select the arable land parcels and provide useful references for the large-scale comprehensive land consolidation,it has important practical values for the protection of arable land and the development of related policies.
