摘　　要：针对长江黄河源区水土资源发展和可持续利用问题,该文基于水土资源生态足迹模型和耦合协调度模型,分析了长江黄河源区2010—2021年水土资源的匹配状况,评估了水土资源可持续发展状态及水土资源承载力耦合协调状态。结果表明:2010—2021年研究区的水土资源匹配状态极差,基尼系数虽然逐渐减小,但仍未达到理想状态;水资源处于可持续发展的状态,生态足迹呈现下降趋势,承载力呈上升趋势;土地资源则处于不可持续发展状态,生态足迹和承载力均呈现下降趋势;水土资源耦合协调状态极差,由于土地资源承载力发展滞后水土资源承载力发展处于失调状态。总体上,长江黄河源区的水土资源状态较差,可持续利用形势严峻,提高源区水土资源的生态承载力,实现水土资源可持续发展,对维护水安全、生态安全至关重要。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.
