Sustainable utilization analysis of water resources in Shiyang River Basin based on ecological footprint mode

Abstract

The contradiction between supply and demand of water resources has become a global issue, which cause that Sustainable utilization of water resources has become an important topic in the world. According to the division of three-level accounts, the ecological footprint and ecological carrying capacity of water resource were calculated by using the ecological footprint model in Shiyang River Basin from 2007 to 2018. On this basis, the ecological surplus and deficit and ecological footprint of ten-thousand-yuan GDP were used to analyze its sustainable utilization. The results showed that the water resources in this region are in an extremely unsafe state of ecological deficit, but the degree of sustainable utilization of water resources is constantly improving. There is a positive correlation between the ecological carrying capacity and rainfall; The ecological footprint of the primary industry is much larger than that of the secondary industry and the tertiary industry, but the utilization efficiency of water resources is the lowest, which is the important reason for the ecological deficit of water resources.
