Key Technologies for Constructing Ecological Corridors and Resilience Protection and Disaster Reduction in Nearshore Waters

The increase of population and economic activities has brought a series of problems to coastal areas, such as ecosystem pollution, overdevelopment, and climate change. The frequent occurrence of natural disasters is threatening the ecosystem of coastal areas, but also seriously affecting coastal populations. Under these circumstances, the construction of coastal ecological corridors, integrated with resilience protection and disaster reduction systems, has emerged as a critical strategy for enhancing the stability of ecosystems. This study combines big data analysis technology, remote sensing technology, and geographic information system (GIS) to establish a real-time dynamic monitoring for ecological corridors. The experimental results show that the average flow velocity in the ecological corridor area significantly slows down after a rainstorm compared to the control area. After the construction of the ecological corridor, the soil erosion rates decreased significantly, while air and water quality showed significant improvements. These findings show that ecological corridors improve the quality and protection efficiency of the ecological environment in coastal areas.
