This article uses the water resource ecological footprint method to analyze the spatial and temporal distribution of water resource ecological footprint and water resource ecological carrying capacity in Chenzhou City and its 11 counties (cities, districts) from 2015 to 2022. The results show that: The ecological footprint of water resources in the past eight years has been mainly based on agricultural water use, followed by industrial water use. The per capita ecological footprint of water resources shows a stable fluctuation, with an average of 0.775 hm2 per person over the years. The ecological footprint of water resources is mainly affected by precipitation, and the overall change is consistent with the trend of precipitation changes;there are differences in the ecological footprint of water resources among 11 counties and districts in Chenzhou City. Zixing City’s ecological footprint of water resources is in the high-water footprint domain, while the per capita ecological footprint of water resources in Guiyang County, Yizhang County, Jiahe County, Rucheng County, and Guidong County are all in the low water footprint domain;water resources in Chenzhou City are constantly in ecological surplus, and local water resources can meet the needs of urban development, laying a solid foundation to achieve sustainable development goals.展开更多
