| Summary: | 碩士 === 朝陽科技大學 === 建築及都市設計研究所 === 96 === The aim of this research is to explore the influences of school green structure, green coverage type and ratio on urban green structure by using the landscape indices. Following survey and analysis on campus buildings and greening types, the greenery quality was revealed. Strategies for greenery were generated through calculation of the Greenery Index of the Green Building Assessment Indices and case studies.
The results show that 30 percent of green coverage of school ground usually can meet the requirement of the Greenery Index and was recommended. The size of such school greening areas is almost equal to that of a neighborhood park in an urban city. The installation of green roof could result in the increases of fragment of landscape structure in urban areas but the total area and density of green land would be increased eventually. Rooftop gardens could be excellent habitats for birds in urban environment.
Circulating type of green coverage for school site provide better connection opportunity to near-by parkway and green corridor so as forming better green network in urban context. When the building coverage ratio of school ground is lower than 20% and the average green covering rate higher than 30%, more than 60% of these schools can meet of requirement of the Greenery Index.
In terms of school greenery, the building boundary retrenched areas and the sounding areas of the school sites have the highest green coverage rate. Those areas were also the most suitable for applying ecological multi-laying greenery practice. The outdoor sport grounds were usually covered by ground covers and lawn. Base on the Greenery Index analysis, around 33% schools surveyed passed the Greenery Index evaluation. For schools that failed to meet the requirement of Greenery Index, the most effective practice was to set roof gardens planting shrubs. The second effective approach was to apply multi-laying plantation to replace the existed solid wall. It was suggested that reach 30% green coverage of school ground is the most important target to fulfill. It not only would increase the passing rate of Greenery Index but also provide more habitats and stepping stones for urban animal migration.
