山东省生产水足迹综合评价

Comprehensive Evaluation of Production Water Footprint in Shandong Province

山东省是经济和人口大省,同时也是水资源紧缺省份。水足迹是认识水资源的新视角,能够揭示对水资源的真实占用。基于水足迹视角构建生产水足迹测度模型和评价体系能对2010-2021年山东省水资源利用情况进行评价。结果表明:2010-2021年山东省生产水足迹波动上升,表现为西部和中南部高、东部和中北部低,蓝、绿、灰水足迹均呈增长趋势。在所有核算账户中,农业占比最大。从综合评价角度看,生产水足迹的经济效益逐渐增长,但单位生产水足迹的人口承载力较差,水资源压力指数较大。山东省总体表现为水资源不可持续,水资源压力较大,应及时采取调整产业结构、提高节水技术、增强污染防治等措施以缓解用水紧张的现状。

As a significant economic and populous region,Shandong Province also grapples with water scarcity.The water footprint concept provides a fresh understanding of water resources,revealing the true utilization extent of the resources.A model and evaluation system for measuring the production water footprint is established to assess water resource utilization in the province from 2010 to 2021.The results indicate that the production water footprint in the studied region experiences fluctuations and presents an overall increasing trend during this period,with higher levels in the western and southern regions and lower ones in the eastern and northern areas.The blue,green,and grey water footprints all display a rising trend.Agriculture accounts for the largest proportion among all the sectors.From a comprehensive perspective,the economic benefits of the production water footprint steadily increase,but the per capita carrying capacity of the production water footprint is relatively poor,with a relatively large water resource pressure index.Generally,Shandong faces unsustainable water resources and considerable water pressure,which highlights the need for timely measures to adjust the industrial structure,enhance water-saving technologies,and improve pollution prevention and control to alleviate current water scarcity.
