碩士 / 東海大學 / 景觀學系 / 102 / Since the industrial revolution, urbanization has been bringing critical negative impacts on water ecology and its functions, resulting in decreasing porous surfaces as well as increasing flood frequencies and urban water pollution. The overuse of land resources through urban development has brought destruction on existing ecolgies, causing impacts in the urban environment and its ecosystems. If good use can be made to flooding and water pollution, great beneficial changes can be brought to the water resources in the city. Rain gardens, also known as bioretention areas, are recommended as the best method to reducing urban pollution, not only does it improve water quality but also brings decisive results in decreasing surface runoff and floods.
This study is aimed at Taichung Tunghai University as its research area. The current planning of the campus has yet to have distinct planning in rainwater and drainage. Creating a better campus environment through rain gardens and connecting the green campus to surrounding river and nature systems can bring signifcant impacts. Thus, the purpose of this research is to 1) gain correlation between different space attributes and the feasibility of installing rain gardens on the campus of Tunghai University's, and 2) gain differentiation of various feasibility factors of installing rain gardens on the campus of Tunghai University's.
The subjects are targeted at teachers and students trained in landscape architecture, architecture and fine arts related professions in Tunghai University. Through literature reviews, descriptive statistics, reliability analysis, factor analysis and correlation analysis, the results suggest that installing rain gardens in the dormitory area as most feasible, followed by the teaching area. Installation of rain gardens in active areas and the administrative areas show a medium level of feasibility, while installation of rain garden in the ranch area and church area show insignificant results.
The results of this study conclude that the dormitory area should be the priority area to install rain gardens on the campus of Tunghai University, not only can it reduce chemical substances in domestic wastewater before being discharged into the underground drainage systems, it can also highly reduce the impact of ecological pollution of nearby rivers. The second priority is the teaching area, where an open air design, instead of an underground system, can bring educational means, allowing for students to better understand the connections between ecological environments, urban hardscapes and rainwater runoffs. The two areas referred to above can be prioritized as demonstrative areas, through observing its construction processes, results and benefits, establishing its advantages and feasibility, the system can then be further extended to other areas of the campus.
