摘要：
Villages are important components of agricultural heritage sites, and their tourism models significantly impact ecosystem service value (ESV). This study takes Zhenglong Village (culture and tourism integration), Ziquejie Village (farmstay type), and Jizhai Village (sightseeing type) with different tourism models in the Ziquejie Terraces heritage site as the research objects. Firstly, a single dynamic land use model and a land use transfer matrix were used to reveal rural land use changes driven by three different tourism models. Secondly, changes in ESV in the three villages were assessed with a valuation model. Finally, the welfare per unit area of villagers obtained from ecosystem services (ESs) was calculated. The results showed that: (1) From 2006 to 2022, the built-up area in the three villages gradually increased, primarily converting from farmland. Zhenglong Village experienced the smallest degree of change in both farmland and built-up areas. (2) The total ESV in Zhenglong Village increased by 0.35 times, the highest among the three villages. (3) Zhenglong Village saw the largest increase in welfare per unit area of villagers, from 82,551 CNY in 2006 to 111,785 CNY in 2022. Therefore, adopting a culture and tourism integration model in this heritage site is most conducive to conserving and enhancing the rural ESV, improving villagers' welfare, and promoting the sustainable development of villages and heritage sites.

Abstract: In the supply chain management, the mechanism of the main body of agricultural products supply chain for food safety is mainly the process control, responsibility tracing and benefit incentive. Through the comparative analysis of effect of the supply chain management mode, whose core is processing enterprises, logistics companies, wholesale markets and supermarket chains, on food safety protection, the agricultural products supply chain management mode based on food safety is proposed. This model emphasizes the mutual coordination and restraint between the main bodies of supply chain, and fully guarantees the quality and safety of agricultural products. However, the effective operation of the model requires the joint cooperation and supervision of all nodes in the supply chain. At the same time, it is also an important guarantee to improve the laws and regulations and to strengthen the government supervision.#@#@#摘要: 在供应链管理中，农产品供应链主体对食品安全的作用机理主要表现为过程控制、责任追溯和利益激励。本文通过比较分析加工企业、物流企业、批发市场和连锁超市为核心的供应链管理模式对食品安全的保障效果，提出了基于食品安全的农产品供应链管理模式，该模式强调供应链主体之间相互协调与制约，全面保障农产品质量安全。但是，该模式的有效运行需要供应链上各节点企业共同合作与监督，同时，完善法律法规和加强政府监管也是重要的保障措施。
