摘　　要：陆地表层复杂的人地关系地域系统是人类活动的载体,同时承载着人类活动产生的环境影响。人地关系动态演进过程体现了人类对环境与自然资源开发和利用的深化。随着我国经济社会的迅速发展、生态系统服务的退化消失,人地系统矛盾日趋尖锐。生态系统服务流对生态系统服务的转化、输送与维持具有重要作用,是自然生态系统与社会经济系统之间的桥梁,能够在人地系统间建立时空连接。以黄河中下游的快速城市化发展地区(河南省郑州市)和生态环境保育区(河南省南阳市)为研究对象,构建生态系统服务供需综合评估框架,揭示中尺度区域人地关系动态演变规律。结果表明:近30年间,郑州市的人均三维生态足迹增长力度大于南阳市,而生态承载力水平小于南阳市。2020年郑州市人均三维生态足迹与南阳市的差值为0.195 9 hm^(2)/人,人均生态赤字是南阳市的2倍、1990年的121倍。由此可知,快速城市化发展地区的生态系统服务供给能力和可持续发展水平远低于生态环境保育区,人地系统矛盾比生态环境保育区尖锐。基于生态系统服务流视角的区域人地系统动态演化评估,可为决策者制定科学、合理的区域生态保护和高质量发展政策提供支持。The complex territorial system of human-land relations on the land surface is the carrier of human activities,and carries the environmental impacts generated by human activities.The dynamic evolutionary process of human-land relationship reflects the deepening of human exploitation and utilization of environment and natural resources.With the rapid development of China s economy and society,the degradation of ecosystem services disappears and the conflict between human and land systems becomes increasingly acute.Ecosystem service flows play an important role in the transformation,delivery and maintenance of ecosystem services,and serve as a bridge between natural ecosystems and socio-economic systems,enabling the establishment of spatial and temporal connections between human and land systems.This study takes the rapidly urbanizing development area(Zhengzhou City in Henan Province)and the ecological environment conservation area(Nanyang City in Henan Province)in the middle and lower reaches of the Yellow River as the research objects,and constructs an integrated assessment framework for the supply and demand of ecosystem services to reveal the dynamic evolution of human-land relationship in the mesoscale region.The results showed that the per capita 3D ecological footprint of Zhengzhou City had increased more strongly than that of Nanyang City during the last 30 years,while the ecological carrying capacity level was smaller than that of Nanyang City.The difference between the per capita 3D ecological footprint of Zhengzhou City and Nanyang City in 2020 was 0.1959 hm^(2)/person,and the per capita ecological deficit of Zhengzhou City in 2020 is twice as large as that of Nanyang City and 121 times larger than that of 1990.It was known that the ecosystem service supply capacity and sustainable development level of rapidly urbanizing development areas were much lower than that of ecological conservation areas,while the human-land system conflict was greater than that of ecological conservation areas.The dynamic evolut
