摘要: 传统生态足迹模型在考虑水资源量时,忽略了水污染和净化所占用的水资源,且水平衡系数选取全球平均水平计算,不能体现研究区域的真实状况。对此,本文利用新的平衡因子和水平衡系数计算方法对传统生态足迹模型进行改进,分析了天津市2012—2022年水资源生态足迹与生态承载力,评价了其水资源可持续利用状况,同时分析了水资源生态压力。结果表明,2012—2022天津市水资源生态足迹最大值为24.41 Mhm2,其中农业用水生态足迹占比最大,水污染生态足迹则呈现明显的下降趋势。生态承载力逐年波动,其年际变化受年降雨量的影响较大。

Abstract: In view of the fact that the traditional ecological footprint model ignores the insufficient water resources occupied by water pollution and purification when considering the amount of water resources, and the water balance coefficient is calculated based on the global average level which can't reflect the actual situation of the study area, this paper uses the new calculation method of balance factor and water balance coefficient to improve the traditional ecological footprint model, analyzes the ecological footprint and ecological carrying capacity of water resources in Tianjin from 2012 to 2022, evaluates the sustainable use of water resources in Tianjin, and analyzes the ecological pressure on water resources in Tianjin. The results showed that from 2012 to 2022, the ecological footprint of water resources in Tianjin was 24.41 Mhm2, of which the ecological footprint of agricultural water accounted for the largest proportion, and the ecological footprint of water pollution showed a significant decrease. The ecological carrying capacity fluctuates year by year, and the interannual variation is greatly affected by the annual rainfall.

Key words: ecological footprint of water resources, ecological carrying capacity, ecological pressure on water resources, ecological footprint model
