| Summary: | 碩士 === 國立臺灣大學 === 生物環境系統工程學研究所 === 102 === Recently, the Eco-city is an innovative idea and rising field. The core value of eco-city is how to merge the development of natural environment and urban areas. As the result, successfully for pulling the natural environment design into urban areas could be advantages to maintain the stability of eco-system.
A firefly plays an important role in food webs and is a reliable indicator of ecosystem health. The species receives great attention in human society and, therefore, increase public awareness of environmental issues. This study was conducted through field investigation to understand the connection between the fireflies and environmental factors. Thirteen sampling sites were located at Yong-Jian Ecological Park, Taipei City. Field surveys were used to collect following data: firefly species richness (Line transect methods), relative humidity (RH), maximum air temperature, minimum air temperature, water surface area, distance between a sampling site and a nearest forest (DSF). The relationship between firefly species richness (Aquatica ficta and Luciola kagiana) and the environmental factors were tested through multiple regression analysis. The results showed that richness of the both species has a negative correlation with DSF. Additionally, number of Luciola kagiana is positively correlated with RH. Constructed grassed swales and natural wetlands were the two ideal habitat types identified in this research. The habitat preference of Aquatica ficta and Luciola kagiana were investigated in this research, and the results of forage ratio could provide suggestions for firefly habitat creation.
