And in this context, Erchong Floodway area shows the possibility of transforming the position from “the margin” to “the center.” Political ecology asserts the inseparability of society and nature in the production of landscapes, but also highlights the interaction between different scales. It is helpful for us to conceptualize the transformation of Erchong Floodway area. The study analyzes the relationship between politics, transformations of landscapes, and environmental identities and actions of the residents through the perspective of “environmental subjects and identities” of political ecology. Furthermore, the study clarifies the interactive process of scale by the “chain of explanation.” In this way, the study depicts the historical process of marginalization and the context of redevelopment of Erchong Floodway area, and then analyzes the possibilities and discusses the environmental subjects that occurred in the historical transformations. On the other hand, this paper also seeks to define the spatial meaning of the boundary line delimited by Erchong Floodway, and to explore the relationship between human and nature. Before Erchong Floodway built, under the agricultural landscape, the boundary drew by people represented the way the people connected with land, including the ridges of field, villages, streams, ditches. When the power of the state come into this place, the dikes designated a new modern border, and drew a line between “the center” and “the margin.” Meanwhile, this area has been led to environmental degradation and marginalization as a result of efforts by state policies. The original boundaries were rewritten with the landscape transformation, while the old boundaries overlap and stagger with the new one. But the boundaries have been imprinted in the bodies and the memories of the original residents. The new landscape is not able to lay over the original residents’ memories about the old one. And the dikes are not able to cut their links with the other side. However, now, 30 years has passed, the links and memories have broken in the younger generation. And the old boundaries will be replaced by the new boundaries by degrees. Along with the strategy of “border-crossing” took the place of “demarcation.” Relations between residents and the riverbank have changed, and “Taipei Metropolitan Park " has become an open space of spatial competition. Moreover, the interactions between different scales became more frequent, and led to new environmental subjects. In recent years, on the basis of New Taipei City’s new policies of “urban livability,” the extensive landscape transformation of waterfront revealed the livable imagination of the authorities and the property developers. It seems that this region is able to be prosperous. However, the residents still have the perception of “being marginal.” In consequence, although the “visible” geographical boundaries – dikes, block the regional development, they also become a barrier between human and nature, yet we still can cross it easily through bridges, causeways and other facilities. But the “invisible” geographical boundary printed in the mind of the residents – the perception of “being marginal” – is not necessarily able to be eliminated through the landscape transformation.二重疏洪道大臺北都會公園政治生態學環境議題與認同Erchong FloodwayTaipei Metropolitan Parkpolitical ecologyenvironmental subjects and identities
