摘　　要：为揭示人类活动影响下干旱区水循环要素演化特征,提高区域水资源利用效率与管理。文中以焉耆盆地为研究区、2000-2020年为研究时段,开展区域自然-社会水循环要素变化特征研究,采用Python语言对GLASS-ET产品进行批量获取与处理,得到研究区域实际蒸散量动态;选取线性倾向估计法和Mann-Kendall趋势检验法,分析区域水循环要素演化特征。结果表明:降水平均值为95.4mm,降水量呈不显著上升趋势;实际蒸散量(AET)波动范围149.4~175.6mm,多年平均AET165.4mm,AET总体呈不显著下降趋势;开都河与黄水沟两条主要河流地表径流量呈不显著下降趋势;地表引水量呈显著下降趋势,地下水开采量呈显著上升趋势。人类高强度的活动和用水方式直接影响着区域水循环要素演化进程,研究结果可为焉耆盆地水资源利用与管理提供理论依据。To reveal the evolution characteristics of water cycle elements in arid areas under the influence of human activities and to improve the efficiency and management of regional water resources,this study takes the Yanqi Basin as the research area,the period of 2000-2020 as the study period,and carries out a study on the changes in regional natural-social water cycle elements.Python language is used to obtain and process the GLASS-ET products in batches,to obtain the dynamically regional actual evaporation during the research period.The linear tendency estimation method and Mann-Kendall trend test method are selected to analyze the evolution characteristics of regional water cycle elements.The results show that the average precipitation was 95.4 mm,and the precipitation showed a non-significant upward trend.The actual evaporation amount(AET)fluctuated in the range of 149.4-175.6mm,with a multi-year average AET of 165.4mm,and the AET overall showed a non-significant downward trend.The surface runoff of two major rivers,Kaidu river and Huangshuigo river,showed a non-significant downward trend.The surface water abstraction showed a significant downward trend,and the groundwater extraction showed a significant upward trend.Human activities and water use practices directly affect the evolution process of regional water cycle elements.The research results provide a theoretical basis for the utilization and management of water resources in the Yanqi Basin.
