气候变化和水资源问题是国际社会共同关注的全球性问题，是影响西北干旱地区生态环境和社会经济可持续发展的重大瓶颈。本文在前人研究成果的基础上指出，西北地区独特的地貌增加了气候系统的复杂性和不确定性。本文分析了该地区社会经济发展和生态安全的关键制约因素，探讨了气候变化对西北干旱地区水资源的影响，明确了西北干旱地区气候变化与水资源研究的共同主题和存在的主要问题，最后根据开展该地区水资源研究的重要性和紧迫性，提出了需要解决的科学问题：一是气候变化对西北干旱地区水资源的影响。 该地区水资源的形成、转化及未来趋势；二是高分辨率区域气候模式与干旱区地表格局水循环模式的双向耦合；三是气候变化和人类活动对西北干旱地区水资源的影响。通过上述思考和讨论，本文旨在进一步明确西北地区气候变化与水资源紧迫问题的研究具体领域，为显着提高我国应对气候变化和水资源短缺的能力奠定坚实的科学基础。
Climate change and water resource issues are global problems of common concern to the international community, and they are major bottlenecks affecting the eco-environment and sustainable socio-economic development in the arid region of Northwest China. On the basis of results from previous studies, this paper points out that the unique landscape of Northwest China increases the complexity and uncertainty of the climate system. This paper analyzes the key constraints on socio-economic development and ecological security in the region, discusses the impact of climate change on water resources in Northwest China, identifies common themes and the main problems present in research on climate change and water resources in the arid northwest region, and finally, based on the importance and urgency of conducting research on the region’s water resources, proposes scientific problems that need to be addressed: first, the impact of climate change on the formation, conversion and future trends of water resources in the region; second, bidirectional coupling of high-resolution regional climate models and water cycle models of arid region land surface patterns; third, the impact of climate change and human activities on water resources of the arid northwest region. Through consideration and discussion of the above, this paper seeks to further clarify specific areas of research on pressing issues related to climate change and water resources in Northwest China, so as to establish a solid scientific basis for significantly enhancing our ability to respond to climate change and water shortages.
