概括

中国的城市人口比农村人口消耗的水量要多得多,这突出了水资源使用的重大不平等. 消费水平是这种差异的主要驱动因素,需要可持续的水资源管理策略.

科学领域:

环境科学环境科学
经济学经济学经济学
可持续性研究可持续性研究

背景情况:

水资源对人类福祉和经济发展至关重要.
水利的不平等分配有助于城市和农村人口之间的水资源差距.
了解城市和农村的水足迹差异对于公平的资源管理至关重要.

研究的目的:

评估中国的县级城市和农村水足迹 (WFs).
从消费的角度来定量评估和解释城市和农村的用水不平等.
为公平和可持续的水资源管理战略提供基础.

主要方法:

使用了改进的多区域输入输出 (MRIO) 表.
纳入解决的城市和农村最终消费数据.
进行了水足迹的高分辨率县级分析.

主要成果:

城市人均WF平均比农村人均WF高2.1倍.
经济发达的城市地区被确定为大型WF的热点.
中国10%的人口 (51个县的城市居民) 消费了全国55.8%的世界粮食基金.
消费水平是主要的驱动因素 (约. 84%) 的城市-农村人均WF差异.

结论:

城市和农村的水足迹差距是中国总体水足迹不平等的重要因素.
城市地区的高消费水平导致了大量的用水差异.
迫切需要平衡社会经济发展和城市化与公平和可持续的用水.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
