Optimization of strategies to promote cropland rotation in the black soil area of Northeast China
摘要
Abstract
The degradation of black soil in Northeast China seriously threatens food security and ecosystem balance in China,and farmland rotation is an effective measure to protect black soil.In order to promote farmland rotation and improve the quality of black soil,the farmland rotation of farmers in the northeast black soil area was taken as the research object,and the government,village collective and farmers were included in the same dynamic game evolution model according to the principle of game theory.Through a numerical simulation,the decision-making characteristics of tripartite subjects under single strategy and combination strategy and the evolution trend of tripartite behavior under the change of policy conditions were compared and analyzed.The behavior characteristics and complex game relationship among relevant stakeholders were explored to optimize the farmland rotation strategy in the black soil area.The results indicate that:The single strategy has a limited effect on improving farmers' willingness to rotate crops and can easily lead to strategy imbalance.The multiple strategies significantly increase farmers' willingness to rotate crops and the game system converges to the ideal state faster.Implementing the single strategy or the combination strategy has significant differences in farmers' rotation behavior.Among them,when the single strategy adopted by the government and village collectives only exceeds the threshold,farmers can actively rotate crops.However,it causes a phenomenon of strategy imbalance;The synchronous implementation of the combination strategy of both reward and punishment can avoid the phenomenon of single strategy imbalance,and the combination strategy promotes the game system to converge to the ideal state faster than the single strategy;The improvement of soil quality and the increase in economic income have a significant positive impact on farmers' crop rotation decisions.Therefore,it is necessary to focus on introducing behavioral outcome feedback and behavioral benefit acquisition strategies,and establishing long-term mechanisms to strengthen farmers' crop rotation behavior.This study provided a scientific basis for promoting crop rotation in the black soil area of Northeast China.关键词
