Abstract: Multi-hierarchy index system for regional land consolidation was established for cultivated land consolidation, virgin land reclamation，disused land reclamation and country residential area consolidation. And land consolidation potentialities were evaluated based on AHP, entropy weight method and synthetically evaluation method in Chongqing. Results indicated that cultivated land consolidation potentialities were the central portion of land consolidation potentialities, and the ratio of input-output and the improved ratio of woodland for cultivated land consolidation which were primary influencing factors in Chongqing. In the same way, virgin land reclamation potentialities and disused land reclamation potentialities were also the significant portions of land consolidation potentialities and the special scope index for virgin land reclamation and the improved ratio of woodland and special scope index for disused land reclamation, which were similarly important factors in Chongqing. Moreover, country residential area consolidation is important to development in the main city zone and neighbor areas.
