Abstract:: [Objective]The aims of this study are to identify the key areas of ecological restoration in western Liaoning with high ecological sensitivity, and to provide a scientific reference for the territorial ecological restoration work in the region. [Methods]The research methods such as morphological spatial pattern analysis(MSPA), landscape connectivity evaluation, circuit theory and other research methods were applied to attempt to connect the land ecological security pattern with the sea ecological security pattern, and to identify key areas for ecological restoration in the western Liaoning region. [Results](1)Total of 42 ecological sources covering an area of 11 619.75 km² had been identified in the western Liaoning region. The ecological sources were mainly distributed in a band from northeast to southwest, with woodland and grassland as the main land use types.(2)There were 95 ecological corridors, including 9 primary corridors, 26 secondary corridors, and 60 tertiary corridors, with a total length of 778.30 km.(3)There were 196 key areas for ecological restoration in territorial space, with 93 total ecological pinch points and 103 ecological barrier points. [Conclusion]The identification of key ecological restoration areas is an important foundation and basis for the ecological restoration of territorial space. Based on a comprehensive analysis of the spatial distribution and current characteristics of land use in the key areas of ecological restoration, the targeted ecological restoration strategies of western Liaoning are proposed.
