气候变化对城市水资源安全的影响及应对策略 -环境工程专业

摘要

随着全球气候变化的加剧，城市水资源安全面临前所未有的挑战。本研究围绕气候变化对城市水资源安全的影响进行了深入分析，并提出了相应的应对策略。本文在气候变化对城市水资源具体影响的部分，详细探讨了降水模式改变、冰川融化、地下水位变化等对水资源量的影响；水质污染加剧、海水入侵、有害物质流入等对水资源质的影响；以及供水系统适应性压力增加、基础设施脆弱性上升和运营维护成本增长等对水资源供应系统的影响。在应对策略部分，提出了提升水资源管理策略、优化水资源配置与利用、建立适应性供水设施以及强化风险管理与应急机制等关键措施。此外，还分析了国内外在应对气候变化和保障城市水资源安全方面的成功案例及其对我国的启示。最后，研究结论概括了主要发现，并指出了研究的不足与未来展望。

Abstract

With the intensification of global climate change, urban water resources security is facing unprecedented challenges. In this study, the impacts of climate change on urban water resources security are analyzed and corresponding countermeasures are proposed. In the part of the specific impact of climate change on urban water resources, this paper discusses the impact of precipitation pattern change, glacier melting and groundwater level change on water resources in detail. The aggravation of water pollution, the intrusion of seawater and the inflow of harmful substances affect the quality of water resources. The effects of increasing adaptive pressure of water supply system, increasing vulnerability of infrastructure and increasing operation and maintenance cost on water supply system are also discussed. In the part of coping strategy, the key measures such as improving water resources management strategy, optimizing water resources allocation and utilization, establishing adaptive water supply facilities and strengthening risk management and emergency response mechanism are put forward. In addition, the successful cases at home and abroad in coping with climate change and ensuring urban water resources security and its enlightenment to our country are also analyzed. Finally, the main findings are summarized in the conclusion, and the shortcomings and future prospects of the study are pointed out.
