碩士 === 國立成功大學 === 都市計劃學系 === 107 === Climate Change has caused various issues to our society and environment. In order to decrease these impacts, planning abundant urban green infrastructure has been seen as one of a significant policy strategy. Green infrastructure provide a variety of social and ecological benefits, from improving mental health to flooding management. In this thesis, we tried to evaluate the benefits of the green infrastructure in Yanshuei River Basin, for the purpose of identifying the synergies and trade-offs of different co-benefits. We utilized Soil ＆ Water Assessment Tool (SWAT) to evaluate the effect of runoff reduction and calculate the accessibility to green infrastructure in different scenarios, including plan orientation, centralized and decentralized green infrastructure planning. Results show that there is spatial heterogeneity exist in the synergies and trade-offs between diverse co-benefits. It provided a new perspective for researchers to have more systematic studies associated with this issue. According to the Green Infrastructure Spatial Planning which we built, the prioritization for green infrastructure siting located at Annan District and North District in Yanshuei River Basin. In addition, the effect of runoff reduction is better with decentralized green infrastructure planning, that is to say smaller units of green infrastructure with a separate configuration are more effective to reduce runoff. Furthermore, the average accessibility to green infrastructure of decentralized green infrastructure planning is higher than centralized scenario. In conclusion, government should consider to plan green infrastructure in a decentralized way to enhance the resilience and sustainability of one area.
