中文摘要:
      利用黄河流域1965-2012年252个观测站日降水资料,分析了黄河流域年极端降水、汛期日极端降水的时空分布特征。研究结果表明:黄河流域年极端降水在空间分布上呈现出从东南向西北递减的特点,不同区域的年极端降水强度有显著空间差异,下游大汶河年极端降水强度最大,内蒙杭锦后旗临河一带年极端降水强度最小。极端降水站数偏多的年份,该年黄河流域总降水量也趋于偏多。汛期日极端降水强度从黄河上游到下游逐渐增强,主要发生在7-8月。
英文摘要:
      Based on the daily precipitation data in the 252 observational stations from 1965 to 2012 in the Yellow River Basin, the temporal-spatial distribution characteristics of annual and daily flood season extreme precipitation were analyzed. The results showed that: the spatial distribution of annual extreme precipitation reduced gradually from southeast to northwest of the Yellow River Basin. There were significant spatial differences in the intensity of annual extreme precipitation in different areas. The region which had the maximum annual extreme precipitation was located in Dawen River of the downstream, and the region which had the minimum annual extreme precipitation was located in Hangjinhouqi and Linhe in inner Mongolia. in the years when there were more extreme precipitation stations, the total annual precipitation tended to be larger in Yellow river basin. During the flood season, the intensity of daily extreme precipitation gradually increased from upstream to downstream in the Yellow River Basin, and it mainly occurred in July and August.
