Abstract:[Objective] The ecological carrying capacity of water resources in Fujian Province was studied, in order to provide a scientific basis for the sustainable utilization of water resources in this area.[Methods] Based on the theory of ecological footprint, the 3D model of water ecology carrying capacity was imposed and the data from 2010 to 2019 in Fujian Province was used, to analyze the water ecological footprint, water ecological carrying capacity and spatial pattern of water resources.[Results] From 2010 to 2019, the general trend of per capita water ecological footprint in Fujian Province showed a decreasing trend with a range of 0.696 hm2/person to 0.928 hm2/person. The per capita water ecological carrying capacity ranged from 2.602 hm2/person to 10.944 hm2/person and was greatly affected by precipitation. Water resources showed ecological surplus. The tendency of ecological footprint of ten thousand-yuan GDP showed an obvious downward trend. The water carrying capacity in the western part was obviously better than that in the eastern coastal area. The water resources footprint depth was 1, and the value of water resources footprint size was below 1 in recent years. Meanwhile, it showed a downward trend.[Conclusion] Water resources are rich in Fujian Province. In recent years, water resources well supported the local development. However, the water carrying capacity in Fujian Province varied greatly from year to year and the spatial distribution is quite different. With the development of social economy, there are still some risks in water resources.
