Abstract: In the present study, Maiji District, Tianshui City was taken as an example, and key evaluation indicators were selected from aspects of natural quality conditions, engineering construction conditions and ecological landscape conditions. The construction sequence evaluation principle was proposed as “overall comprehensive evaluation, cultivated land quality vary, and easy projects first”. By comprehensive evaluation coefficient method and natural break method, the construction sequence in Maiji District was evaluated, and reasonable arrangements for the construction mode were proposed. The results showed that the construction scale in the near, medium and long-term should be 17.54%, 51.87%, 30.59%, respectively. These results could provide references for the excellent-criterion farmland construction in Maiji District and the loess hilly and gully region.

Key words: excellent-criterion farmland, time sequence, comprehensive evaluation coefficient method, Maiji District
