概括
黄河流域可持续的水资源利用受到日益严重的水资源短缺和水足迹与城市发展之间的不稳定协调的挑战. 社会经济因素和政策对水资源管理产生重大影响,需要针对SDG 6采取适应性战略.
科学领域:
- 环境科学 环境科学
- 水资源管理 水资源管理
- 可持续发展 可持续发展 可持续发展
背景情况:
- 发展中国家面临着对水资源的巨大压力,阻碍了可持续发展目标6 (SDG6) 在河流流域的实现.
- 黄河流域 (西区) 是平衡水资源利用与快速发展所面临的挑战的一个例子.
研究的目的:
- 评估2005-2019年黄河流域 (山西部分) 的可持续水资源利用情况 (SWRU).
- 分析社会经济系统和政策对SWRU的影响,使用合协调模型和DPSIR框架.
主要方法:
- 使用水足迹 (WF) 和水行星边界 (WPB) 分析水资源过载.
- 使用水源基金和城市发展指数 (CDI) 评估水资源利用质量.
- 结合协调模型和驱动压力状态冲击响应 (DPSIR) 框架的应用.
主要成果:
- 观察到WF的显著时空变化,其中广州的WF波动,山西北部的WF呈现持续增长.
- 确定了水资源赤字状态的持续增长趋势.
- 尽管增加了500.31%,但世界金融基金和CDI之间的协调仍然不平衡和不稳定.
结论:
- 社会经济发展和政府政策对SWRU的影响比水资源供给更大,其影响在空间上有所变化.
- 由于这些多方面的影响,在盆地实现SDG 6是复杂的.
- 适应性水资源政策和加强盆地管理对于促进可持续发展目标6至关重要.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
63
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...

Quality of Water
117
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
