碩士 === 中國文化大學 === 景觀學系 === 101 === In recent years, rapid changes in cities have posed significant and abnormal influences on natural environment. Human beings’ living quality has been severely impacted by the changes. Due to this, take Erching discharge channel, that is located the core of the megalopolitan Taipei City, the place used to be Chautsaiwei wetland, farmlands, then became a ground with unapproved constructions. Finally, serious because the flood risk, the discharge channel has been constructed here until now. For sure, the ecological structure here has been changing acutely. After finished building Yuanshantzu flood diversion channel, flood risk rate has reduced, and this area has become a sport park. Therefore, all changes here are probably destructive of habitat restoration. For this reason, this study would like to probe into that if Erchong has other feasibilities of developmental orientations. Existing urban park systems have no clear definition for “natural park” while in 2010 amendments to the National Park Act has added “Natural Park” as a new category; therefore, the present study aimed to use river wetland as a new category to investigate how to apply ecological planning method to facilitate ecological functions of urban river corridors and also how to apply wetland construction method to map out Erching flood discharge channel, the base of the case study, as an urban natural park. By means of understanding functions of ecological structure and public sectors’ ways and policies to improve ecological functions for rivers, discussing the optimal model of space planning and land uses for natural parks as well as other countries’ ways and related cases for this issue, the study attempted to propose a space planning method that improves ecological functions for rivers and applied it to the research base. The results showed that “wetland restoration” is an important measure to improve urban ecological functions. By using wetland environment as main body, infrastructure of urban ecological environment research can be established. Moreover, through the research suitable planning and design guidelines for ecological values of urban park green systems, diversification of urban landscape ecology can be enhanced. For giving consideration to flood prevention, ecology, education, and recreation, this study looks forward to that the planning of the "Natural Park" would help Erching flood discharge channel to be more sustainable development.
