Land use structure optimization for Guanzhong Region,Shaanxi Province

Based on the analysis of the present land use structure and existing problem related to such land use patterns in Guanzhong Region,Shaanxi Province,this paper applies gray linear programming model (GLP) to the optimization of land use structure in the Region.Several typical solutions for the future land use structure have been simulated out by the model,through the selection of a set of factors deciding land use structure,and through the calculation of parameters of land supply,land use requirements and limitations,and various land use demands.The optimized scheme of future land use structure for the Region has been decided at the end with the analytic hierarchical programming method (AHP) in which both comprehensive benefits and feasibility are considered.
