Sustainable land use is the foundation of sustainable development and the basic link for the coordination of population, resources and environment. Population growth and social-economic development make land demand and daily increase, the contradiction between people and land becomes more and more prominent, and become the bottleneck that restricts economic growth and the improvement of people's living standard. In order to realize the sustainable use of land, strengthen the management of land resources and optimize the allocation of land resources, this paper constructs a multi-objective land use planning model, sets up land use type variables through the current situation analysis, and realizes the optimal economic, social and ecological comprehensive benefits under the constraints of the present situation and planning related indicators. Constructing the multi-objective optimization model of land use structure, this method has strong practicability, and the planning scheme should coordinate the relationship between population, resources and environment well in the planning period, and obtain the maximum comprehensive benefit.
