中文摘要	为了深入了解黄河流域未来水资源变化的时空分布规律,把Mann-Kendal方法(M-K)趋势分析的功能与重标极差分析(R/S)持续性分析的功能相结合,通过分析流域未来气象要素变化特征,揭示黄河流域未来水资源时空丰枯变化特征。结果表明,在年际方面,黄河中游南部区域(占流域面积5.36%)未来水资源供给形势乐观,黄河中游的中部区域(占流域面积29.42%)未来缺水风险增加。在年内方面,黄河流域未来水资源季节供给形势空间分布差异显著。随着春夏秋冬季节的演变,黄河中游中部和南部愈加湿润,北部愈加干旱;黄河流域水资源供给情况相同的区域相对集中。
英文摘要	This paper presents a trend analysis of Mann-Kendal (M-K) coupled with a persistence analysis of rescaled range analysis (R/S) on the changes in meteorological factors to better understand the temporal and spatial distribution characteristics of future water resources changes in the Yellow River basin. The results show that for the middle reach of the river in future, on an annual average, water supply will have an optimistic outlook in its southern region (an area proportion of 5.36%) while the risk in water shortage will increase in the central region (29.42%). In different seasons of a year, the spatial distribution of water supply will be significantly different. Along with seasonal change from spring to winter, both the central and southern regions are becoming increasingly more humid, while the northern region increasingly more arid. In addition, the areas with the same water supply conditions are relatively concentrated.
