摘要:

【目的】通过计算分析黄河沿线各省区水资源生态足迹时空分布特征，以期为黄河沿线水资源科学开发与持续利用提供基础依据。【方法】利用生态足迹模型计算了黄河沿线九省区的水资源生态足迹，并利用基尼系数和对数平均迪氏指数法对水资源生态足迹进行分析。【结果】黄河沿线各省区人均水资源生态足迹存在较大的空间差异性，对水资源生态足迹的贡献呈现为生产用水>生活用水>生态用水；除四川、陕西和青海，其他省区水资源生态处于不可承载状态；各省区的水资源生态足迹与GDP、人口、水资源总量和耕地面积的均衡性均较差；影响水资源生态足迹的主要因素是技术效应和经济效应，其中水资源生态足迹与技术效应成反比，与经济效应成正比。【结论】总体上，黄河沿线各省区水资源生态状况均较差。

Abstract:

【Objective】 Water resource footprint is an important indicator of healthy and sustainable use of water resources in a region. This paper analyzes the spatiotemporal variation of ecological footprint of water resources in the provinces in the Yellow River basin.【Method】 The ecological footprint of the water resources was calculated using an ecological footprint model, and it was then analyzed using the Gini-coefficient and the logarithm average Divisia index. 【Result】There was a significant spatial difference in ecological footprint of water resources per capita between the nine provinces, with the contribution of usage of different water resources to the footprint ranked in industrial water usage > domestic water usage > ecological water usage. In all provinces but Sichuan, Shaanxi and Qinghai, the ecology of water resources is unsustainable, and the balance between the footprint and GDP, population, total water resources and cultivated land is poor. The main factors impacting the footprint are technology and economy, with the footprint inversely proportional to the former while proportional to the latter.【Conclusion】 Overall, the ecological status of water resources in all provinces in the Yellow River basin is poor.
