The aim of this study is to analyze local attitudes toward Guandu Nature Park from a political ecology perspective. This study argues that Guandu Plain is a rural-urban interface, and Guandu Nature Park as a landscape in this interface has been contested for landscape meanings by different interest groups (especially old-timers and newcomers). Thus, different social groups have various, even competitive attitudes toward the park. Through the analysis of value conflicts and scale debates, three topics, namely conservation, landscape resources, and the reward policy from the Park, are discussed. The study results can contribute to future studies of interface in Taiwan, and to future analysis in land use changes in the Guandu Plain.
