| 摘 要： | 黄土高原粗泥沙集中来源区为治理黄河泥沙的重点核心地区.根据1960-1999年黄土高原粗泥沙集中来源区皇甫川、孤山川I、窟野河,秃尾河和佳芦河径流及输沙资料,以流域为单元,分析了区内各流域径流量、输沙量的年内、年际变化特征及变化趋势.结果表明,区内径流量及输沙量的年际、年内变化较大.在季节上,除秃尾河径流量集中期为6月份外,其余4条流域径流量的集中期均为8月份;5条流域输沙量的集中期均为8月份.各流域径流量、输沙量的突变时间均在20世纪70年代,说明各流域水沙量呈现减少的趋势,尤以20世纪90年代减少最明显.人类活动和气候变化是影响该区内各流域水沙变化的主要因素. |

| Abstract: | The paper analyzes the change characteristics and trend of runoff and sediment using water and sediment data observed in the coarse sand source regions of the Loess Plateau from 1960 to 1999.The changing characteristics of runoff and sediment had a great variation during the study period.Concentrated time for runoff occurrence in the studied watersheds was in August,except Tuwei River watershed where the time was in July.Concentrated time for sediment occurrence in the studied watersheds was all in August.Abruptly changed time for both runoff and sediment in the five watersheds was all in the 1970's and after that time,runoff and sediment had a decreased trend,especially in 1990's.Human activities and climate change are the main influence factors. |
| Keywords: | runoff sediment load coarse sand source region the Loess Plateau |
