ABSTRACT

Water resource is the basic resource of Shiyang River basin, and also the most critical resource for the development and progress of Shiyang River Basin. The study of ecological carrying capacity through water ecological footprint is conducive to solving the contradiction between domestic water and ecological water, realizing the efficient utilization and sustainable development of water resources, and has a far-reaching impact on the overall planning of regional water resources and the harmonious development of economy, society and nature. This study used a model to calculate the ecological footprint and ecological carrying capacity of water resources in the Shiyang River Basin over the past 10 years and discussed the coupling relationship between them using a correlation analysis method. The results showed that the ecological footprint of water resources in the Shiyang River Basin was positively correlated with water consumption and there was no obvious linear relationship between the ecological footprint of water resources and ecological carrying capacity. The variation in the ecological footprint of water resources in the Basin with the total population was small and the variation in the ecological footprint of water resources was positively correlated with the variation in water consumption. The ecological carrying capacity of water resources was directly proportional to the total population and annual runoff. The results are of great significance for the optimisation of water resources in the Shiyang River Basin and provide decision support for water resource management and planning in the basin.
