基于MAS的梯田非粮化农户行为决策机制与模拟
Decision-making mechanism and simulation of non-grain use behavior of farmers on terraced fields based on MAS
摘要
Abstract
To explore the operational logic of farmers' non-grain use behavior on terraced fields,this study based on Multi-Agent System(MAS),combined field surveys and multi-scenario simulations to investigate the decision-making mechanisms of farmers in terraced field utilization in the Longzhong and Longdong regions.The results indicated that the intrinsic mechanism of farmers' decision-making in terraced field utilization was primarily aimed at maximizing economic benefits,with household resource endowment exerting a stronger constraining and guiding influence,while the external natural,social,and policy environments provided additional incentives or constraints.Specifically,the weight ratios of internal and external environmental variables in the three study areas were 0.486∶0.514,0.575∶0.425,and 0.538∶0.462,respectively.The decision-making behavior of farmers in terraced field utilization in the Longzhong and Longdong regions showed a trend dominated by non-grain use with grain production as a supplement.The final decision values for non-grain use in the three study areas were 0.852,0.842,and 0.942,respectively.Farmers in the study areas exhibited spatial heterogeneity in their perceptions,feedback values,decision values,and main environmental variables regarding different terraced field utilization methods.In multi-scenario simulations,grain production incentive policies had a significantly positive impact on increasing farmers' decision values for grain crops.Market saturation of non-grain uses could effectively curb non-grain use driven by economic crops and attract labor backflow,thereby effectively alleviating the phenomenon of land abandonment.Finally,targeted strategies for optimizing the pattern of agricultural non-grain use were proposed to provide references for promoting sustainable rural development.关键词
