「景觀」已跳脫傳統風貌綠美化或實體環境營造，逐漸發展成為「動態、複合、感知」之多重整合意涵，「地景」一詞即可表達此概念，並意謂地景經營之重要性。食物地景蘊含在地人、環境、文化與行動之間的緊密鏈結關係，跨族裔地區更可呈現出豐沛的動能及多元發展的趨勢，蘊含「食物串聯」、「社會網絡」、「跨文化脈絡」等實踐理念。本研究為「鄉村」為主體的參與式規劃行動研究，以桃園龍潭與龍岡跨族裔地區為研究對象，探討食物在地景發展過程中的影響力，以及累積在生活地景中的層層軌跡。研究發現有三：（一）龍潭舊街區的食物設計行動展開跨文化地景整合的實踐策略；（二）高原社區公民農業行動建構社區照護與物質循環的食物地景；（三）龍岡多元族裔的遷徙與融合呈現計畫性的經濟活動與跨文化的交流，促成族裔之間的相互關照，形成療癒性的食物地景。綜言之，食物社會設計以創新培力之在地著根模式，引導人及社區從自身的改變提升到公共利益的思維與行動，促進在地社區的健康福祉與永續發展，形成一種創新的社會發展轉型與社區照護理念。

The management of landscape has changed from traditionally scenic green beautification or physical construction to an approach towards multiple, integrated meanings of dynamics, complex and perception, showing the importance of landscape management. Foodscape contains the close relationship among local people, environment, culture and action. Multi-ethnic areas can show more energy and multi-development trends, which involve food connections, social networks, and multi-cultural contexts. This study is a participatory action research, focusing on multi-ethnic areas located in Longtan and Longgang, to explore the effects of food on landscape development and their layers accumulated in our lifescapes. It is found that food design action in Longtan old districts shows a practice strategy that integrates multi-cultural landscapes. Civic agricultural activities in Gaoyuan community develop a foodscape with community care and material cycle. The immigration and integration of multiple ethnicities in Longgang indicate planned economic activities and multi-cultural interactions. This encourages mutual care and restorative foodscape. In summary, food-oriented social design shows an innovative, empowering, enrooted-locallysystem that leads people and communities from self-development to public participation, promotes local welfare and sustainable development, and establishes a newer type of societal development and idea of community care.
