摘要
水资源利用合作制约着京津冀区域协同发展政策实施。根据地区经济发展水平和用水量补偿生态环境保护投入成本,解决京津冀区域间水资源环境保护不均衡问题。基于虚拟水足迹模型,对京津冀行政区水足迹与水盈余/赤字的空间变化进行研究,构建生态补偿标准模型,量化京津冀三省市间生态补偿额度。衡量地区降低水足迹(即虚拟水足迹总量)的紧迫性并识别调整重点,为构建京津冀特色水安全保障体系提供依据。在此基础上,给出京津冀针水资源合作补偿机制,为京津冀生态环境共建共享提供参考。
Cooperation in the utilization of water resources restricts the implementation of Beijing-Tianjin-Hebei region coordinated development policy. According to the regional economic development level and the cost of compensation for protecting water ecological environment, the countermeasures for solving Beijing-Tianjin-Hebei regional problem of water environmental imbalance is studied in this paper. Based on virtual water footprint model, the water footprint and spatial change of water surplus/deficit of Beijing-Tianjin-Hebei region are studied and an ecological compensation standard model is built to quantitatively calculate ecological compensation amount between the three provinces of the Beijing-Tianjin-Hebei region, the urgency of reducing the water footprint ( i.e., the total virtual water footprint) is evaluated and the focus is adjusted to provide basis for establishing water security system of Beijing-Tianjin-Hebei. On this basis, the Beijing -Tianjin-Hebei water resources cooperation compensation mechanism is put forward to provide the reference for the co-construction and sharing of ecological environment of Beijing-Tianjin-Hebei.
