【摘要】 西北旱区水资源短缺,生态环境脆弱,严重制约了社会经济可持续发展和生态环境良性循环。尤其是在变化环境下,全球气候变暖加快了冰川融化速率,西北旱区的水文要素和水资源都发生了剧烈变化。因此,综述西北旱区水文水资源科技进展与发展趋势具有重要的意义。本文在大量查阅国内外水文和水资源科技研究文献的基础上,简述了西北旱区水文水资源特点和存在问题,对水文水资源科技进展进行了较系统总结;同时,指出了旱区水文水资源科技的发展趋势,可为进一步研究旱区水文水资源关键学科问题和关键技术提供有益参考。更多还原

【Abstract】 The shortage of water resources and the fragile ecological environment has seriously restricted the sustainable development of social economy and the virtuous cycle of ecological environment, in the northwest arid region, especially in the changing environment. Global warming has accelerated the melting rate of glaciers, and the hydrology and water resource have undergone drastic changes in the northwest arid region. Therefore, it is of great significance to summarize the progress in science and technology and development trends of hydrology and water resources in northwest arid region. Based on the study of a large number of progress in science and technology and development trends of hydrology and water resources at home and abroad, the main research objectives of this paper are to: analyze the characteristics and existing problems of hydrology and water resources in the northwest arid region, systematically summarize the progress in science and technology of hydrology and water resources, points out the development trend of hydrology and water resources in the northwest arid region, which can provide beneficial reference to further study the problems of hydrology and water resources in the northwest arid region.更多还原
