摘　　要：运用2020年商洛市土地利用类型图、高程数据、坡度数据、河流数据、道路数据,通过MSPA、MCR模型识别了10个生态源地和45条生态廊道。研究发现,商洛市的生态源地分布不均匀,南部缺乏稳定的生态源地,重要的生态廊道只有18条。基于此研究结果,建议在商洛市南部国家级自然保护区和主要风景区增设4个生态源地,53条生态廊道,并结合研究区交通网络和地形状况,提出增设14块脚踏石,修复185个断裂点,以优化商洛市的景观格局,为提升区域生态建设修复提供参考。The land use type map,elevation data,slope data,river data and road data of Shangluo City in 2020 are used to identify 10 ecological sources and 45 ecological corridors by using MSPA and MCR models.It is found that the distribution of ecological sources in Shangluo City is uneven,there is no stable ecological source in the south,and there are only 18 important ecological corridors.According to the research results,4 ecological sources and 53 ecological corridors were added to the southern national nature reserve and the main scenic spots in Shangluo City.Combined with the traffic network and terrain conditions in the study area,it was proposed to add 14 pedal stones and repair 185 break points to optimize the landscape pattern of Shangluo City,so as to provide reference for improving regional ecological construction and restoration.
