摘　　要：为深入探讨土地利用多样性对生态系统服务的影响,并提出一种创新的耦合模型优化策略。通过这种策略,可以最大化土地利用多样性与生态系统服务价值,从而促进农业生产、生态环境保护与人类福祉之间的和谐发展。为了实现这一目标,构建了一个综合模型,涵盖了作物生长、土地利用变动、生态系统服务评价、多目标优化4个关键模块。这个模型全面模拟并解决作物系统设计问题,考虑了农业生产、生态环境和人类福祉等多个目标和约束。通过实证分析,比较了不同土地利用配置方案的效果,以寻求最优或接近最优的选择。结果发现:优化作物情景在提升生态系统服务价值和人类福祉指数方面表现最佳。该情景不仅确保了农业生产的高效率,还在生态系统服务供给和人类福祉方面取得了显著成效。这一发现证明了多样化的土地利用配置能够带来更多的生态和社会经济效益。本研究的创新之处在于,首次将作物系统设计问题定义为多目标优化问题,并通过耦合模型进行实证分析。这一方法论为农业生态系统管理提供了新的视角和工具,有助于实现可持续发展目标。本研究结果强调了土地利用多样性在提升生态系统服务价值和人类福祉方面的重要性,为未来的土地管理政策和实践提供了科学依据。This paper aimed to investigate the impact of land use diversity on ecosystem services and propose an innovative coupling model optimization strategy.Through this strategy,we could maximize the diversity of land use and the value of ecosystem services,thereby promoting the harmonious development of agricultural production,ecological environment protection and human well-being.In order to achieve this goal,we constructed a comprehensive model covering four key modules:crop growth,land use change,ecosystem service evaluation and multi-objective optimization.The model comprehensively simulated and solved crop system design problems,taking into account multiple goals and constraints such as agricultural production,ecological environment,and human well-being.Through empirical analysis,we compared the effects of different land use allocation schemes to find the optimal or near-optimal choice.The study found that optimized crop scenarios had the best performance in improving the value of ecosystem services and human well-being index.This scenario not only ensured efficient agricultural production,but also achieved significant results in the provision of ecosystem services and human well-being.This finding proved that diversified land use allocation could bring more ecological and socio-economic benefits.The innovation of this study was that for the first time,the crop system design problem was defined as a multi-objective optimization problem,and the coupling model was used for empirical analysis.This methodology provided new perspectives and tools for agroecosystem management to help achieve the sustainable development goals.Our findings highlighted the importance of land use diversity in enhancing the value of ecosystem services and human well-being,providing a scientific basis for future land management policies and practices.
