本研究從環境正義的觀點，探究關西118外環道開發爭議與環境因素的關聯，從而提出臺灣民意與政策的關鍵落差與建議。研究方法上，本研究主要從社會脆弱性（Social Vulnerability）觀點，來探討居民對於環境變遷適應能力，並以之為基礎，發展出強調社會韌性（Resilience）的ESAR質性研究架構。 研究發現，居民普遍認為開路並不能帶來關西的經濟發展，反而會造成市區商業的沒落、環境的污染和破壞，顯現出民意期待與政策執行的落差，而造成這種民意與政策落差的原因，可能與資訊接受不全有關。在地居民、地方政府與在地非營利組織等不同利害關係人，對於118外環道開發呈現了不同的風險認知。地方政府、民代與村里長則對於在地居民所呈現出的價值、在地經驗、文化並未高度重視，顯示開闢道路政策並未考量關西地方的特殊性。 在政府的公共政策上，地方居民的環境權與參與權被忽視，顯示現行的制度與地方居民參與機制的不健全，使得118外環道開發決策過程產生環境不正義，促使在地居民發起環境行動，透過自身的行動表達自己的意見，捍衛環境權與環境正義。;This study examined residents’ responses to the government-proposed new road plan for the rural Township Guansi of Taiwan. Main dispute about road plan is its potential impacts on functions of farmlands that characterize the traditional township and its cultural landscape. On research design, we first constructed a conceptual framework on Exposure-Sensitivity-Adaptability-Response （ESAR） causal relationship. Based on the framework, semi-structured interviews were conducted in sensitive communities potentially exposed to future road construction addressing both built-environmental sensitivity and residents’ adaptability. In addition, remote sensing technology was used to identify the urban sprawl that leads to this environmental change. As a result, throughout interview analysis classified by both natural capital （land, water and wildlife） and human capital （experience, health, and network）, Township Guanxi showed preparedness for a changing environment caused by road plan. We argue that risk perceptions play a crucial role in organizing residents’ inaction, resistance, and adaptation to environmental change. Environmental movements are underscored in promoting further political transition. We conclude that the current experience of locals with the road plan provides insights into adaptive behavior of the local Hakka people on dealing with future environmental change while recognizing the need of economic development.
