Optimization of Multi-Objective Crop Pattern Based on Water and Fertilizer Resources Allocation

Abstract:

To enhance the utilization efficiency of water and fertilizer resources, and improve agricultural ecological environment in resettlement area, a crop planting structure optimization model was established by the use of multiple objective linear programming (MOLP) method, and solved by two-phase algorithm. In this model, multiple targets, such as the economic, social and ecological benefits of this region were taken into account. The results showed that the MOLP model and its solution were feasible and practical. The optimized area of rice, corn and tobacco reduced by 16%, 100% and 76% respectively, and the optimized area of wheat and sugarcane increased by 82% and 78% compared with the current planting area. And the net economic and social benefits increased by 4% and 62%. The optimization scheme played a guiding role in the adjustment of agricultural structure, and promoted the sustainable development of agriculture in resettlement area.
