摘要

随着全球努力应对气候变化的深刻影响,水资源短缺已成为一个紧迫问题。然而,对于像中国兰州这样的干旱和半干旱地区,水资源依赖与经济、生态和社会需求之间的权衡,却缺乏深入的研究。兰州的花卉种植严重依赖黄河水,往往忽视了天然降水的潜力。在这里,我们首先在兰州的一个水土保持示范园区通过人工降水实验校准了一个水平衡模型。然后,我们建立了一个多目标优化模型,在经济、生态和社会等方面平衡各种可行措施的成本效益,以寻求更能适应气候变化和当地发展需求的解决方案。模型模拟结果表明,我们设计的解决方案可以有效管理缺水天数,大幅减少黄河取水量,提高成本效益,满足所研究公园 66%-80% 的花卉种植用水需求。研究结果凸显了雨水收集和利用解决方案在缓解干旱和半干旱城市缺水问题方面的潜力,从而丰富了水资源管理。

A multi-objective optimization approach for harnessing rainwater in changing climate
As the world grapples with the profound impacts of climate change, water scarcity has become a pressing issue. However, there is a shortage of in-depth research on the trade-offs between water resource dependence and the economic, ecological, and social needs of arid and semi-arid regions like Lanzhou, China. Flower cultivation in Lanzhou relies heavily on the Yellow River, often overlooking the potential of natural rainfall. Here we first calibrated a water balance model through artificial precipitation experiments in a Soil and Water Conservation Demonstration Park in Lanzhou. We then developed a multi-objective optimization model to balance the cost-benefit considerations of various plausible measures across economic, ecological, and social dimensions in the searching for solutions that are more adaptable to climate change and local development needs. Model simulations show that the solutions we designed can effectively manage water-shortage days, significantly reduce Yellow River water extraction, and improve cost-effectiveness, meeting 66%–80% of water needs for flower cultivation in the studied park. The findings highlight the potential of rainwater collection and utilization solutions to mitigate water scarcity in arid and semi-arid cities, thereby enriching water resource management.

期刊介绍: Advances in Climate Change Research publishes scientific research and analyses on climate change and the interactions of climate change with society. This journal encompasses basic science and economic, social, and policy research, including studies on mitigation and adaptation to climate change. Advances in Climate Change Research attempts to promote research in climate change and provide an impetus for the application of research achievements in numerous aspects, such as socioeconomic sustainable development, responses to the adaptation and mitigation of climate change, diplomatic negotiations of climate and environment policies, and the protection and exploitation of natural resources.
