摘　　要：基于“三生”空间视角构建土地利用多功能评价指标体系,运用改进的熵权TOPSIS法评价新一线城市南京市的土地利用多功能及其时变特征、权衡协同关系与障碍因素等,得到的结果显示:南京市在研究期间内土地利用多功能呈倒U型变化趋势,其中生产功能和生活功能提高,生态功能呈衰退态势;南京市土地生产、生活、生态功能空间存在程度不一的协同权衡关系;土地生产功能与生态功能的障碍度持续增大,其中SO 2年均浓度、森林覆盖率影响较突出,生活功能的障碍度持续减小。因此新一线城市应在权衡土地生活、生产与生态功能协同关系中强化土地生态空间服务功能,减少生活与生产活动带来的生态负效应,引导土地功能向高度协调方向演化。In a multi-functional land use evaluation index system established based on the ecological-living-productive space,an improved entropy weight TOPSIS method was used to evaluate the multi-functions of land use in the new first-tier city of Nanjing,and its time-varying characteristics,trade-off synergy and barriers,and so on.The results showed that:the multi-functions of land use in Nanjing showed an inverted U-shaped trend during the study period,in which the productive and living functions were increased and the ecological functions were declining,there were different degrees of synergy and trade-off between the productive,living and ecological functions of the land in Nanjing,and the barriers between the productive and ecological functions of the land continued to increase,among which the annual average concentration of SO 2 and forest coverage had a significant effect,and the degree of disturbance of living function decreased continuously.Therefore,the new first-tier cities should strengthen the ecological spatial service function of land and reduce the negative ecological effects brought by living and productive activities in the balance of the synergistic relationship between land living,productive and ecological functions,and guide the evolution of land functions to a highly coordinated direction.
