碩士 / 義守大學 / 土木與生態工程學系 / 104 / Fishing port is an important part of coastalengineering. Tidal flats are the habitat of many terrestrial and aquatic organisms, therefore fishing port structures will become the ecological impacts of tidal flat. Liugiu is an off-shore island of Taiwan. It was located at the southwest site of Taiwan. Since Kuroshio and other ocean currents were crossed to Liugiu, it has the high biodiversity. SanFu sightseeing fishing port is one of the fishing ports in Liugiuisland and it is locaterd at the biggest tidal flat of Liugiu island. Therefore, the aims of this study are used some statistical softwares, such as Benthic Index of Biotic Integrity (B-IBI) and Shannon-Weaver Index, to analyze the ecologicalbiodiversity changes. After that we used Pearson correlation coefficient to analyze the correlation and estimated the ecological impacts of tidal flat by SanFu fishing port. Finially, we will provide some suggestions and strategies to improve these ecological impacts. According to the results of this study, we found that the Pearson correlation coefficient of average trend and variation percentage of whole year B-IBI showed the high negative correlation (-0.904). It means that domestic polluted water from the right site of fishing port should be the factor of tidal flat ecological impacts. Secondly, the Pearson correlation coefficient of average trend of whole year Shannon-Weaver Index and variation percentage of 9 combination B-IBIs showed the high posttive correlation (0.771). It means that clipping blocks from the leaf site of fishing port might decrease the migratory ability of organisms and cause the decrease of biodiversity. In the end, the ecological phases of outer fishing port were better and worse inside the fishing port. This finding showed that the SanFu sightseeing fishing port should cause the ecological impacts of Liugiu tidal flat.
