The ecological control area is importantly ecological space of preventing the disorderly spread of urban construction and guaranteeing the ecological security of city. The hierarchical management of the ecological control area can play a full role in maintaining urban ecological security and promoting the coordinated development of urban construction and ecological protection. Based on multi-source data fusion, this study used the method of ecosystem service importance-ecological sensitivity-landscape connectivity to identify ecological source areas, and used the Minimum Cumulative Resistance (MCR) model to determine ecological corridors and important ecological nodes. With the interlacing of points, lines and faces, an ecological security pattern network is constructed to adopt to the ecological control areas hierarchical division in Xiamen. The results show that there are 17 ecological source areas in Xiamen, covering area of 604.19 km², accounting for 35.54% of the area of Xiamen, including the ecological red line area, water source protection areas, and forest parks etc. The number of key ecological corridors is 15, with a length of 152.84 km, which are mainly mountain and sea ecological corridors connecting the main ecological source with the sea. The number of ecological nodes is 22, which are mainly small important protection areas outside the ecological source area and areas with clear ecological protection objectives. According to the ecological security pattern, the ecological control areas of Xiamen are classified into three levels. The ecological source area, ecological corridor and ecological node can be classified into the first-level control area, accounting for 69.48% of the total area. The ecologically important areas and forestland outside the first-level control area can be classified into the second-level control area, accounting for 10.15%. The other areas within the ecological control area are classified into the third-level control area, accounting for 20.37%. On this basis, suggestions on hierarchical management and control are put forward in order to provide important reference for Xiamen to realize high-level protection of ecological management and control areas and high-quality development of the city.
