The can play a full role maintaining promoting coordinated development protection. Based on multi-source data fusion, this study used method ecosystem service importance-ecological sensitivity-landscape connectivity to identify source areas, Minimum Resistance (MCR) model determine corridors important nodes. With interlacing points, lines faces, an network constructed adopt areas division Xiamen. results show that there are 17 Xiamen, covering 604.19 km2, accounting for 35.54% including red line area, water protection forest parks etc. number key 15, with length 152.84 km, which mainly mountain sea connecting main sea. nodes 22, small outside clear objectives. According pattern, classified into three levels. corridor node be first-level 69.48% total area. ecologically forestland second-level 10.15%. other within third-level 20.37%.
