Deterioration of Coastal Ecosystem: A Case Study of the Banana Bay Ecological Reserve in Taiwan

Due to the increasing pressure on the environment from human activities, there is a growing need to understand the relationship between species and the environment. Therefore, this study constructs life cycle and niche from a geographic perspective, aiming to explain how existing spatial configurations affect the deterioration of coastal ecosystems. This research mainly adopts the method of literature analysis and field investigation, and then carries out four steps of reading, sorting, integration and analysis. In this study, the road kill data and living environment data of land crabs were integrated, and two results were obtained on the relationship between spatial conflict areas and land crab populations. The first is that the life cycle of land crabs is disturbed by TPH 26, thus confirming the spatial conflict hypothesis; the peak period of traffic flow at TPH 26 overlapped with the peak period of land crab larvae release, indicating that the spatial configuration of the reserve is not only a spatial conflict, but also a spatial-temporal conflict. Second, the land crab is an important indicator of coastal forests, and its niche also reflects geographic diversity, especially in features such as topographic structure, geological stability, and environmental humidity.
