Abstract: Optimal allocation for prime farmland protection area is a decision-making process. Ranking cultivated land synthetically and selecting cultivated land into prime farmland protection area are the two logical correlated parts of the process. Based on the characteristics of the two processes, this paper presents an attribute hierarchical ranking model what based on attribute measure and a zero-one integer programming selecting model. And a decision-making system of optimal allocation for prime farmland protection area was integrated by applying the second-developed technology of MAPGIS. The system was demonstrated in Dongshe Country, Wanbolin District, Taiyuan City. The results showed that the decision-making models can solve the decision-making problem of optimal allocation for prime farmland protection area at local level effectively, and the research also provides a new method for the optimal allocation of territorial land use.
