基于水资源生态足迹的马鞍山市水资源可持续利用评价

Evaluation of Sustainable Utilization of Water Resources in Ma'anshan Based on Water Resources Ecological Footprint

以水资源生态足迹模型为基础,综合研究马鞍山市2016-2021年统计得出的各项相关数据。马鞍山市2016-2021年水资源生态足迹呈波动下降趋势,其值范围为0.0439-0.0552 hm^(2)/人,马鞍山市人均水资源承载力在0.0011-0.0043 hm^(2)/人之间,人均水资源赤字在0.0405-0.0530 hm^(2)/人之间,水资源负载指数的均值数据是20.10,万元GDP水资源生态足迹年平均降低12.46%。分析结果表明,马鞍山市水资源利用效率显著提高,水生态压力有所减小,但水资源仍处于不可持续状态。通过对马鞍山市水资源可持续利用现状进行分析评价,以期为区域未来水生态文明建设和可持续发展提供相关支持。

Based on the model of water resources ecological footprint,this study comprehensively studies the relevant data of Ma'anshan from^(2)016 to 2021.The ecological footprint of water resources in Ma'anshan shows a fluctuating downward trend from^(2)016 to 2021,with a range of 0.0439 to 0.0552 hm^(2)/person.The per capita water resource carrying capacity of Ma'anshan was between 0.0011 to 0.0043 hm^(2)/person,and the per capita water resource deficit was between 0.0405 to 0.0530 hm^(2)/person.The average data of the water resource carrying index was 20.10,and the annual average water resource ecological footprint of 10 thousand RMB Gross domestic product(GDP)decreased by 12.46%.The analysis results indicate that the utilization efficiency of water resource in Ma'anshan has been significantly improved,and the water ecological pressure has been reduced,while the water resources are still in an unsustainable state.By analyzing and evaluating the current situation of sustainable utilization of water resources in Ma'anshan,we aim to provide relevant support for the future construction of water ecological civilization and sustainable development in the region.
