[Objective] This study aims to accurately identify key nodes and regions of ecological protection, and to construct ecological corridors in a reasonable way for the sustainable development of the ecosystem. [Methods] Taking Xinzhou City as a case study, this research proposes an ecological security pattern construction method, which is based on the paradigm of ‘ecological source-resistance surface-ecological network'. The ecological source is identified by combining the evaluation of ecosystem service value and morphological spatial pattern analysis(MSPA). The resistance surface is constructed based on entropy weight method and multi-resistance factor. The circuit theory is used to simulate and analyze ecological corridor and ecological nodes. [Results](1)A total of 59 ecological sources covering an area of 2 355 km2 were identified in the study area, showing a spatial distribution pattern of eastern concentration and central and western dispersion.(2)Additionally, the study identified approximately 100 ecological corridors(with a total length of 1 637.58 km), 111 ecological pinch points(with a total area of 3.16 km2), and 83 ecological obstacle points(with a total area of 48.7 km2)in the study area. According to the important values, ecological corridors showed an annular distribution from inside to outside. And the ecological pinch points mainly distributed in the adjacent areas between the ecological source area and corridor. [Conclusion] Building an ecological security pattern can effectively identify the ecological corridor and the key areas for ecological restoration. In the process of ecological protection and restoration, ‘protecting corridors, repairing pinch areas, removing and improving obstacle areas' should be taken as a general strategy.
