摘　　要：生态足迹与生态承载力密切联系,可用于衡量区域可持续发展水平。依据西安市年度统计资料,采用生态足迹模型,深入分析城市生态环境状况。结果表明,2013—2021年,人均生态足迹增长约50%,达到0.287 3 hm^(2),而平均生态承载力减少50%以上,从0.148 8 hm^(2)降低到0.128 2 hm^(2)。随着经济的高速发展,西安市面临的生态压力变大,应加大生态环境领域的投入。Ecological footprint is closely related to ecological carrying capacity and can be used to measure the level of regional sustainable development.Based on the annual statistical data of Xi’an city,the ecological footprint model is used to conduct a comprehensive analysis of the urban ecological environment.The results showed that from 2013 to 2021,the per capita ecological footprint increased by about 50%,reaching 0.287 3 hm~2,while the average ecological carrying capacity decreased by more than 50%,from 0.148 8 hm~2 to 0.128 2 hm~2.With the rapid development of the economy,Xi’an city is facing increasing ecological pressure and should increase investment in the field of ecological environment.
