摘要
河西地区是甘肃省的关键农业生产区之一,随着人口增长、经济发展和气候变化,当地面临巨大的水资源压力。以水资源生态足迹法为手段,深入剖析河西地区水资源可持续利用现状。数据分析发现,2013—2022年,河西地区水资源可持续利用取得显著成果,农业用水效率和水资源利用效率明显提高。但是,水资源生态承载力不足,水资源供需关系不平衡,水资源压力指数波动大,仍面临较大的挑战。
The Hexi region is one of the key agricultural production areas in Gansu Province,with population growth,economic development,and climate change,the local area has faced enormous water resource pressure.Taking the ecological footprint method of water resources as a means,the current situation of sustainable utilization of water resources in Hexi region is analyzed in depth.Data analysis finds that from 2013 to 2022,significant achievements had been made in the sustainable utilization of water resources in the Hexi region,with a significant improvement in agricultural water use efficiency and water resource utilization efficiency.However,the ecological carrying capacity of water resources is insufficient,the supply-demand relationship of water resources is unbalanced,and the water resource pressure index fluctuates greatly,still facing significant challenges.
