摘　　要：针对区域生态网络优化布局及生态保护修复策略构建问题,以陕西省咸阳市为研究区,在生态本底评价基础上,结合形态学空间格局分析、最小累积阻力模型和电路理论,提出了咸阳市域生态网络优化格局及生态保护修复策略。结果表明:咸阳市2020年农业生产空间占主体,其次为自然生态空间和城镇生活空间;2000—2020年间北部林地和南部建设用地显著增加,中北部地区植被覆盖度呈增加趋势,生态系统服务显著提升;基于此构建的基础生态网络包含108个生态源地、229条生态廊道、313个关键生态夹点和347个障碍点,并结合地区规划建立了背靠山塬俯瞰渭水的“三区-四源-两带-多廊-多点”市域整体性生态网络优化格局及分区分类的生态保护修复策略。研究结果可为国土空间生态保护修复关键区识别及保护修复策略构建提供空间明确的信息支撑。Aiming at the regional ecological network and adaptive protection and restoration strategies,the ecological evaluation and Morphological Spatial Pattern Analysis combined with Minimum Cumulative Resistance model and circuit theory were conducted in the Xianyang City of Shaanxi Province which was selected as the study area.The results shown that the area of agricultural production space accounted for the largest proportion in 2020,followed by the natural ecological space and urban living space.During 2000—2020,the forestland in the north and the built-up land in the south increased significantly.Besides,the vegetation coverage increased significantly in the central and northern regions and the key ecosystem services were improved significantly.Based on this,the ecological network was constructed including 108 sources,229 corridors,313 pinch points,and 347 barriers.A series of adaptive ecological protection and restoration strategies for the optimized ecological network of“three districts-four sources-two belts-multiple corridors-multiple nodes”were proposed based on the regional planning.The results can provide spatially explicit implications for the identification of critical areas and appropriate strategies of territorial ecological protection and restoration.
