Optimization of Land Use Zoning Based on Goal Programming and Simulated Annealing

In this paper,Yuzhong County in Lanzhou City was selected as study area.An approach based on Goal Programming and Simulated Annealing was applied for land use zoning in this area,with land suitability,planning coordination and spatial compactness as zoning objectives.Results show that the zoning plans under different scenarios reflect the goals of decision-makers.The new generated plan over-performs the original one in the aspects of zoning objectives and meets the requirements of agricultural production,economic development and ecological protection.
