Wuhan and Shiyan cities in Hubei Province were selected as comparative cases. A landscape ecological risk assessment model was constructed to evaluate the level of conflicts among production-living-ecological spaces (PLES) and their spatiotemporal characteristics. A spatial error model was then used to investigate the impact effects of urbanization and ecological construction on PLES conflict. We further analyzed the moderating role of ecological construction in mitigating such conflicts during urbanization. The study reveals that from 2000 to 2020, Wuhan was dominated by production-ecological space, while Shiyan was characterized by ecological-production space. In Wuhan, the PLES conflicts showed a “core-periphery” structural characteristic, with the conflict level gradually intensifying and predominantly characterized by moderate and weak conflict types. In Shiyan, the conflicts exhibited a pattern of higher in the north and lower in the south, with conflict levels trending downward and the proportion of weak conflict types continued to increase. Economic urbanization helped alleviate conflicts in both cities, while land urbanization exacerbated the conflict levels. Population urbanization mitigated conflicts in Wuhan but intensified in Shiyan. Furthermore, ecological development in Wuhan strengthened the exacerbating effect of land urbanization on PLES conflicts, while in Shiyan it enhanced the mitigating effect of economic urbanization and the intensifying effect of population urbanization. The research findings provide scientific evidence for formulating differentiated optimization strategies in territorial space development and protection patterns in different types of cities.

选取湖北省武汉市和十堰市作为案例, 通过构建景观生态风险评估模型, 评估三生空间冲突水平及时空变化特征。运用空间误差模型, 探究城镇化和生态建设对三生空间冲突的影响效应, 并进一步分析城镇化进程中生态建设对三生空间冲突的调节作用。结果表明, 2000—2020年, 武汉市以生产–生态空间为主导, 十堰市则以生态–生产空间为主导。武汉市三生空间冲突呈现“核心–边缘”的结构特征, 冲突水平总体上渐趋加剧, 以中等及弱冲突类型为主; 十堰市三生空间冲突呈现北高南低的态势, 冲突水平整体上呈下降趋势, 表现为弱冲突类型的占比持续提升。经济城镇化有助于缓解两市的三生空间冲突, 土地城镇化则加剧冲突水平。人口城镇化在武汉市表现出减缓冲突的作用, 在十堰市却加剧冲突。此外, 生态建设在武汉市强化土地城镇化对三生空间冲突的加剧效应, 在十堰市则增强经济城镇化对冲突的减缓作用和人口城镇化的加剧效应。研究结果可为制定不同类型城市的国土空间开发保护格局差异化优化策略提供科学依据。
