The theme of my paper is to investigate the influential factors on Tainan's environmental movement in 1990s, and the merits of the movement. Tainan's case deals with the conflict between ecologism and economic development. The location of the confrontation is in Qi-gu area. The argument is about whether the government should permit the Project of Binnan Industrial Construction in order to improve the living condition of local people, or should conserve the wetland as a habitat for the endangered species, so-called 'Blackface flat-beak crane.' In my paper, Ⅰ discuss the issue from two perspectives of history: one is the policy of tidal land utilization since 1950, and the other is the execution of Kyoto Protocol on Feb.15, 2005. My research shows that the regulation on green house effect, and the conservation on wetland and endangered species, are so important and powerful ideas and can't be ignored. Therefore, under the global trend of environmental protection, the conservation issue in Taiwan can't break away from the logic of global environmental politics. The result, to change the former policy of tidal land utilization becomes natural and necessary. My paper argues that under the impact of the global trend of environmental protection and political dynamics in local society, the environmental politics of anti-Binnan movement in Tainan area has made the movement itself as the most complicated one in Taiwanese ecological movements since 1980s, however, we still have to wait for more historical development in the future to evaluate its achievement.
