二重疏洪道工程環境的的政治生態學分析（一）－劃界（1960－1996）

Political ecology emphasizes 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 among politics, transformations of landscapes, and environmental identities and residents' actions through the perspective of of political ecology. Furthermore, the study clarifies the interactive process of scales 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 issues 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. Trace back to the historical transformation of Erchong Floodway area, during the period of construction, the policies of the state authorities were led by the discourse of ＂flood control,＂ however, it actually implied the identity of ＂the center＂ and ＂the margin.＂ Meanwhile, this area has been led to environmental degradation and marginalization as a result of efforts by state policies.
