英文摘要	The Beijing-Tianjin-Hebei region in China is experiencing a serious ecological water scarcity problem in the context of climate warming and drying. There is an urgent need for practical adaptation measures to cope with the adverse impacts of climate change and provide a scientific basis for urban water supply planning, water resource management, and policy formulation. Urban ecological water can maintain the structure and function of urban ecosystems, both as an environmental element and as a resource. Current research lacks quantitative analysis of the impact of regional meteorological factors on ecological water use at the small and medium scales. Based on the meteorological data and statistical data of water resources in the Beijing-Tianjin-Hebei (BTH) region, this paper analyzed the trend of climate change and established an ecological climatic water model using gray correlation analysis, polynomial simulation, and singular spectrum analysis to predict the ecological water consumption. And, we assessed the climatic sensitivity of ecological water use and estimated the future ecological climatic water use in the BTH region based on four climate scenarios' data. The results showed that the average multi-year temperature was 13.2 degrees C with a clear upward trend from 1991 to 2020 in the BTH region. The multi-year average precipitation was 517.1 mm, with a clear shift in the period of abundance and desiccation. Ecological climatic water modeling showed that a 1 degrees C increase in temperature will increase ecological water use by 0.73 x 10(8) m(3)similar to 1.09 x 10(8) m(3) in the BTH region; for a 100 mm increase in precipitation, ecological water use will decrease by 0.49 x 10(8) m(3 similar to)0.88 x 10 m(3); under the four climate scenarios of SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5, the regional ecological climatic water use will be 5.14 x 10(8) m(3), 6.64 x 10(8) m(3), 7.82 x 10(8) m(3), and 9.06 x 10(8) m(3) in 2035, respectively; and in 2050, the ecological climatic water use will be 8.16 x 10(8) m(3), 9.75 x 10(8) m(3), 10.71 x 10(8) m(3), and 12.41 x 10(8) m(3), respectively. The methodology and results of this study will support the quantification of climate change impacts on ecological water use in the BTH region and serve as a theoretical basis for future research on ecological water use adaptation to climate change. This study can provide a basis for the development of the overall planning of urban ecological water supply, and at the same time, it can lay a foundation for the study of measures to adapt to climate change by ecological water use.
