【摘要】 食物关系国计民生,中国食物系统面临诸多挑战,耕地资源趋减、环境压力临界、农业劳动力流失、消费需求快速转型等对食物系统功能提出更高要求,地理学的综合性和系统性思维为应对这些问题提供了有效的工具和视角。尽管食物系统得到世界银行、联合国粮农组织以及其他国际各方的高度关注,但目前国内对食物系统的研究却严重不足。论文对食物系统的认知进展进行了深入分析,归纳了食物系统的概念认知历程、类型、特征,梳理出食物系统的研究脉络,包括从"概念"存在到"方法"存在、从线性认知到系统认知、从经济活动到食物景观、从现象描述到时空嵌入等,以此凝练出食物系统的核心内涵与认知进展;在科学哲学范式、人地关系范式、空间范式和系统科学范式指导下,论文遵从"格局—结构—过程—机理"由表及里的研究脉络,进一步探讨了食物系统的时空格局、要素结构、演化过程和发展机理,尝试构建了食物系统的地理学研究范式,研究结论旨在为推动食物系统视角基础研究和实践应用提供参考和借鉴。更多还原

【Abstract】 Food is related to the national economy and people’s livelihood. China’s food system is facing many challenges. The reduction of cultivated land resources, criticality of environmental pressures, loss of agricultural workforce, and rapid transformation of consumer demand have placed higher demands on food system functions.At the present in China, food system research is insufficient and the research content is fragmented, which cannot meet the needs and challenges of the society today. This article provides an in-depth analysis of the evolving concept of food system, summarizing the conceptual issues and types and characteristics of food systems. It then examines the progress of food system research, which evolved from concepts to methods, from a linear to a systematic recognition of the concept, from economic activities to food landscapes, from phenomenon descriptions to spatiotemporal analysis, among others, to consolidate the core connotation of the food system.Under the guidance of the human-environmental relationship paradigm, the spatial paradigm, the philosophy of science paradigms, and the systematic science paradigm, and following the path of "pattern-structure-processmechanism," the spatial and temporal patterns, factor structure, evolution process, and development mechanism of food systems are further explored. The aim of this study is to construct a geographical paradigm of food system research. It intends to provide some references for promoting basic research and practical applications of a food system perspective.更多还原
