摘　　要：文章以河谷城市甘肃省兰州市为例,在测度“三生”空间冲突强度并揭示多尺度分异机制的基础上提出冲突协调策略。结果显示:①“三生”空间格局演化与地域分异显著。生活空间的增加主要源于对生态空间和生产空间的侵占。②兰州市“三生”空间冲突时空演化与地类分异显著。时序上,“三生”空间冲突强度呈持续上升态势,整体处于基本可控级别;空间上,形成了“一心、两翼、多轴带”的空间冲突格局;就地类而言,城镇的生活空间与生产空间冲突水平较高。③兰州市“三生”空间冲突影响因素尺度效应和异质性明显。高程、坡度、地形起伏度等对“三生”空间冲突具有抑制作用;人口密度、人均G D P、夜间灯光指数等因素加剧了区域“三生”空间冲突程度。Taking the valley city of Lanzhou city in Gansu province as an example,the article proposed a conflict coordination strategy based on measuring the conflict intensity of the"production-living-ecological"spatial conflict and revealing the multi-scale differentiation mechanism.The results show that:①The spatial pattern evolution and regional differentiation of"production-livingecological"space are significant.The increase in living space mainly stems from the encroachment on ecological space and production space.②The temporal-spatial evolution and land type differentiation of the"production-living-ecological"spatial conflict in Lanzhou city are significant.Temporally,the intensity of the"production-living-ecological"spatial conflict is continuously increasing,and the overall level is basically controllable.Spatially,a spatial conflict pattern of"one center,two wings,and multiple axis zones"has been formed.In terms of land type,the conflict level between living space and production space in the town is high.③The scale effect and heterogeneity of the factors influencing the"production-living-ecological"spatial conflict in Lanzhou city are obvious.Elevation,slope,and topographic relief have an inhibiting effect on the"production-living-ecological"spatial conflict,while population density,per capita GDP,and nighttime lighting index have exacerbated the conflict degree of the regional"production-living-ecological"space.
