| 以洛阳市为研究对象，基于1990—2020年4期遥感影像解译数据，构建“三生”用地主导功能分类体系，运用PLUS模型模拟2030年“三生”用地特征，深入揭示“三生”用地转型下洛阳市生态系统服务价值响应特征及其内在权衡协同关系。结果表明：30年来城镇生活用地、乡村生活用地增幅明显，农业生产用地逐年减少（-24081km2），水域生态用地小幅增加（+8839km2）；生态系统服务功能整体呈增强趋势，总价值增长1303亿元。在耕地保护、生态保护、自然发展、经济发展4种模拟情景下，生态系统服务价值在研究区西北上升、东南下降。2030年洛阳市城镇生活用地持续扩张，林地生态用地区域性蔓延，促使生态系统服务价值不断提升，各项生态系统服务协同关系明显，权衡关系较少且主要存在于支持与文化服务之间。 |

| Taking Luoyang as the research object， based on 4 periods of remote sensing image interpretation data from 1990 to 2020， this study constructed a classification system for dominant functions of production land， living land and ecological land， used PLUS model to simulate the features of production land， living land and ecological land in 2030， and analyzed the response characteristics of ecosystem service value in Luoyang and its inherent tradeoffs and synergies under the transition of production land， living land and ecological land. The results indicated that in the past 30 years， the growth rate of urban and rural living land was significant， the agricultural production land decreased year by year（-240.81 km2），and the ecological land in waters increased slightly（+88.39 km2）. The overall trend of ecosystem service function was increasing， with a total value growth of 1.303 billion yuan. Under four simulated conditions of farmland protection， ecological conservation， natural development and economic development， the value of ecological service increased in the northwest and decreased in the southeast of the study area. By 2030 in Luoyang， the urban living land would continue to expand， the ecological land in woodland would expand regionally. The value of ecosystem service would continue to increase， synergies between ecosystem services would be evident， with fewer tradeoffs and mainly between support and cultural services. |
