| Summary: | 碩士 === 國立臺北科技大學 === 土木與防災研究所 === 93 === The growing complexity of the city infrastructures creates complex ecosystems that are unique to the urban environment. In addition, human activities also create serious issues such as habitat loss, habitat fragmentation, and loss of biodiversity. It was pointed out that the creation of ecological ponds in cities could mitigate these adverse effects but the argument was never proved with scientific evidences. Therefore, it is the purpose of this research to use video camera motoring technique to analyze the effect of ecological ponds and assess their values on the urban ecosystems.
This research used the ecological pond located on the campus of the National Taipei University of Technology as the subject of study. First, information from other schools was collected as reference data. Then, video cameras were installed to monitor the activities of the pond on a 24-hour basis. Finally, a mathematical model was proposed to analyze the probability of birds discovering the newly added pond in an urban environment. The results proved that the ecological pond, although small in size, could be used by various bird species as a food source, and the size effect of the pond could be determined from the mathematical model for planning purposes.
