Abstract

Taking Kaiyuan City as an example, this paper has constructed the ecological security pattern and identified the key areas of ecological restoration from the perspective of ecosystem services and ecological vulnerability. The ecological problem index was used to quantify the existing ecological problems in the key areas of ecological restoration, and the ecological restoration zoning was delineated and the corresponding restoration strategies were proposed. The research showed that: (1) The ecological security pattern of Kaiyuan City consisted of two sources and two types of corridors. The area of ecological protection source and ecological restoration source was 190.53km² and 16.82km² respectively, and the total length of potential ecological corridor and restoration corridor was 191.15km and 75.71km respectively. (2) Based on the ecological security pattern, the key areas of ecological restoration in Kaiyuan City were extracted, including 15 ecological restoration sources, 12 ecological restoration corridors, 31 ecological pinch points and 11 ecological obstacle areas. The rocky desertification in the key areas of ecological restoration was mainly concentrated in the west and south of Kaiyuan city, and the degree of rocky desertification in the west was higher than that in the south. Soil erosion was mainly micro-erosion; geological disasters occured frequently in mining areas and karst landform areas; ecological risks were high; human disturbance was concentrated in the northwest-southeast line. (3) According to the calculation results of ecological problem index, the key areas of ecological restoration were divided into ecological conservation areas, functional improvement areas, disaster prevention areas and key remediation areas, and corresponding optimization strategies were proposed in combination with the prominent ecological problems in each area. The research results could provide some reference for the identification and restoration strategy of key areas of territorial space ecological restoration.
