Abstract: Potential analysis of newly-increased cultivated land becomes an increasingly important part of the feasibility research for the spatial-temporal allocation of land development and consolidation project and quantity-quality balance of land requisition-compensation. Based on the perspective of newly-increased cultivated land on unit area, in this paper, potentialities of the newly-increased cultivated land from cultivated land consolidation, rural residential consolidation, unutilized land development and land reclamation were calculated by the method of conversion in accordance with grade, respectively. The various potential rank zones of newly-increased cultivated land on unit area were identified by hierarchical clustering method. Moreover, the contribution rate of the newly-increased cultivated land from land development and consolidation was studied. Results indicated that there were significant regional differences of newly-increased cultivated land on unit area from the four different types of land development and consolidation in Chongqing, in which cultivated land consolidation the northeast of low, medium mountains areas and the southeast of medium mountainous areas, rural residential consolidation the western of mountain and hilly areas, unutilized land development the western of mountain and hilly areas and the central of parallel to the ridge valley hilly areas, and land reclamation the western of mountain and hilly areas also with the northeast of low, medium mountains areas and the southeast of medium mountainous areas. Not only can the newly-increased cultivated land on unit area calculated by the method of conversion in accordance with grade closely link the quantity and quality of the newly-increased cultivated land to the grade distribution of the occupied cultivated land in Chongqing, but also can weak the influence of the total areas of land development and consolidation in different county on the real potential analysis of newly-increased cultivated land. Therefore, the results can provide scientific instruction for the spatial-temporal allocation of land development and consolidation project to make regional cultivated land requisition-compensation balance possible.
