摘要:

区域水资源安全评价对指导水资源科学管理、促进经济社会与水资源绿色发展具有重要意义。针对传统水资源生态足迹法中缺少水资源生态与经济社会发展之间的联系,引入水资源生态效益率,通过改进的水资源能值生态足迹法,对西安市的水资源安全和可持续发展状况进行分析。结果表明,2011—2019年西安市水资源承载力随降雨量波动较大,水资源生态承载力年均值为0.160 hm2/人,水资源生态足迹年均值为1.521 hm2/人,整体处于呈减小趋势的水资源生态赤字状态;区域万元GDP水生态足迹从2011年的0.057 hm2/人下降到2019年的0.019 hm2/人,说明水资源利用效率得到提升;2011—2019年,西安市水资源生态压力指数相对较高,但从5.79下降到4.39,达到相对安全状态,且水资源压力指数和生态效益率的协调发展分布较集中,水资源生态效益随区域水资源压力的缓解而增大。总体而言,西安市水资源安全形式仍然紧张,未来可以通过经济发展方式与水资源配置的优化来促进区域高质量可持续性发展。

Abstract:

The evaluation of regional water resources security plays a crucial role in guiding the scientific management of water resources and promoting the green development of the social-economy and water resources. The traditional water resources ecological footprint method lacks the connection between water resource ecology and socio-economic development. To address this, we introduce the water resources ecological benefit ratio to improve the emergy analysis method for water resource ecological footprint and then analyze the water resource security and sustainable development status of Xi’an City. Results reveal that from 2011 to 2019, the water resources carrying capacity fluctuated in line with annual rainfall. The average annual water resources ecological carrying capacity was 0.160 hm2/cap, while the average annual water resources ecological footprint was 1.521 hm2/cap. An obvious decreasing ecological deficit of water resources was observed. The regional water ecological footprint per 10 000 yuan of GDP declined from 0.057 hm2/cap in 2011 to 0.019 hm2/cap in 2019, indicating an improvement in water resources utilization efficiency. During 2011-2019, the water resources ecological tension index remained relatively high but decreased from 5.79 to 4.39, approaching a relatively safe level. Moreover, the water resources ecological benefit increased as the water resources stress alleviated. However, the water resources security situation in Xi’an remains severe. In the future, it is necessary to optimize the economic development mode and water resource allocation to promote high-quality sustainable development in Xi’an.

Key words: water resources security, improved energy ecological footprint, ecological carrying capacity of water resources, ecological benefit ratio of water resources, Xi’an city
