Analysis of coupling coordination degree of ecological carrying capacity of water and soil resources in source region of Yangtze River and Yellow River
Based on the ecological footprint model and coupling coordination degree model of water and soil resources,this article analyzes the matching status of water and soil resources in the Yangtze and Yellow River source areas from 2010 to 2021,and evaluates the sustainable development status and coupling coordination status of water and soil resources carrying capacity.The results show that the matching status of soil and water resources in the study area from 2010 to 2021 is extremely poor,and although the Gini coefficient gradually decreases,it has not yet reached the ideal state;Water resources are in a state of sustainable development,with a decreasing ecological footprint and an increasing carrying capacity;Land resources are in an unsustainable state of development,with a decreasing trend in ecological footprint and carrying capacity;The coupling and coordination status of water and soil resources is extremely poor,and due to the lagging development of land resource carrying capacity,the development of water and soil resource carrying capacity is in a state of imbalance.Overall,the water and soil resources in the source areas of the Yangtze and Yellow Rivers are in poor condition,and the situation of sustainable utilization is severe.Improving the ecological carrying capacity of water and soil resources in the source areas and achieving sustainable development of water and soil resources are crucial for maintaining water and ecological security.
