摘要 以开远市为例,从生态系统服务和生态脆弱性视角,构建生态安全格局并识别生态修复关键区域;以生态问题指数识别生态修复关键区内存在的生态问题,划定生态修复分区并提出相应的修复策略.研究表明:(1)开远市生态安全格局由两种源地和两类廊道构成.其中生态保护源地和生态修复源地的面积分别为190.53和16.82km2,潜在生态廊道和修复廊道总长分别为191.15和75.71km.(2)基于生态安全格局提取开远市生态修复关键区域,包括15个生态修复源地、12条修复廊道、31个生态夹点和11个障碍区.生态修复关键区域内石漠化主要集中于开远市西部和南部,西部石漠化程度较南部更高;土壤侵蚀以微度侵蚀为主;地质灾害多发于采矿区以及喀斯特地貌区;景观生态风险均较高;人为干扰集中在西北—东南一线.(3)根据生态问题指数(Ecological Problem Index)测算结果,将生态修复关键区域分为生态保育区、功能提升区、灾害防治区和重点整治区,并结合各区突出生态问题提出相应的优化策略.
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.
