Abstract: The paper aims to solve the problem of matching the allocation of urban land resource with economic construction requirement to the greatest extent degree, so that convenience to realize the objective of maximizing the comprehensive benefit of urban land use. Take the municipal districts of Hohhot city as a case study area, combined with the structure of urban land use change characteristics in the area from 2001 to 2016, respectively using the goal programming method and analytic hierarchy process to forecast and merit land demand scheme in 2030 based on the objects of economy and society benefit, and simulate space layout and make decision for the optimization scheme of the best benefit target of the above two kinds of target by CLUE-S model. The results showed that: (1) the total area of urban construction land in the study area increased to 94.104% from 2001 to 2016, with the land used of the biggest increase of the two types for the transportation land and residential land. (2) Different from present situation of the urban land use structure change trend, the biggest growth of the urban construction land classes are commercial land and industrial and mineral storage land respectively based on the optimization target of economic benefits and social benefits, and the equilibrium degree of the two kinds of schemes of urban construction land use structure are higher than the status values of 2016 year are 0.259 and 0.462 respectively, the urban construction land kind composition in the area tends to be dynamically balanced development momentum. (3) The forecast urban construction land area of economic benefit optimization scheme is 30.828 km2 higher than the social benefit scheme. Starting from the theoretical principle of achieving the best comprehensive benefits of land use, due to that the social benefit optimization scheme is better than the economic benefit plan in the dynamic balance of urban land structure and layout, and it becomes the best urban land optimization scheme.
