Abstract:: [Objective] The Yellow River water catchment ecological function area of Gannan is a typical ecological environmental fragile area. Quantitative clarification of the human-environment interaction and its influencing factors is of great significance to realize the ecological security and high-quality development of the Yellow River Basin. [Methods] The intensity of human activities, resource and environmental carrying capacity and the relationship between them in the Yellow River water catchment ecological function area in Gannan from 2005 to 2019 were calculated and evaluated by using the linear weight method. And the response model and geographic detector were used to analyze the spatiotemporal evolution and influencing factors of human-environment interaction. [Results] The intensity of human activities continued to increase, the carrying capacity of resources and environment had experienced ‘good-decline-limited recovery' from 2005 to 2019. The comprehensive state of human-environment relationship presented the evolution characteristics of medium-high loose, medium-low tension and medium-high tension, and there were apparent differences between north and south areas. The human-environment relationship in pastoral and semi agricultural and semi pastoral areas was tighter than that in agricultural areas. The effect of the intensity of human activities on the carrying capacity of resources and environment reflected significant characteristics of spatial-temporal evolution. In the temporal evolution, the effect of human activity intensity on the carrying capacity of resources and environment presented ‘stress effect' weakening-‘promotion effect' decreasing-‘stress effect' enhancing. In the spatial evolution, the effect of the intensity of human activities on the carrying capacity of resources and environment in Hezuo city presented the change from ‘stress effect' weakening to ‘promotion effect' strengthening. The effect in Linxia, Hezheng and Jishishan counties had showed from ‘promotion effect' to ‘promotion effect' weakening since 2015, while the effect for the Kangle, Lintan, Zhuoni, Maqu, Luqu and Xiahe counties showed that the ‘promotion effect' weakening to the ‘stress effect' increasing. The development level of animal husbandry, population density and per capita net income of farmers and herdsmen were the main driving factors for the spatiotemporal evolution of human and environment relations, and the interaction between the factors showed a nonlinear enhancement and a two-factor enhancement relationship. [Conclusion] The human-environment interaction in the Yellow River water catchment ecological function area of Gannan was on a tense trend, and there was a obvious spatial heterogeneity. In the future, the green transformation of animal husbandry and the improvement of farmers' livelihood capabilities should be strengthened so as to achieve the human-environment coordination and high-quality development.
