摘要:Based on the water resource data and economic data from 2006 to 2017, this paper analyzes the temporal and spatial variation characteristics of sustainable water resources utilization in Yan'an, using a water ecological footprint model and the ten-thousand-yuan GDP water resource ecological footprint, combined with the ecological carrying capacity and ecological deficit principle. The result shows that the overall wave of the water resources ecological footprint in Yan'an rises but not in an obvious way, but the ecological carrying capacity and the ecological deficit of water resources are fluctuating. Production water accounts for the largest proportion in the water resources ecological footprint. Affected by industrial transformation, the industrial water consumption in Yan'an has increased year by year and ranked the first by exceeding agricultural irrigation water in 2009. The ecological footprint of water resources in Yan'an has always been greater than its ecological carrying capacity, and the water supply has been in an ecological deficit state; in general, the ten-thousand-yuan GDP water resources ecological footprint has decreased obviously, while the resource utilization has gradually been increasing. However, consumption on water resources by economic development is still faster than resource regeneration.
